+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+We as members, contributors, and leaders pledge to make participation in our
+community a harassment-free experience for everyone, regardless of age, body
+size, visible or invisible disability, ethnicity, sex characteristics, gender
+identity and expression, level of experience, education, socio-economic status,
+nationality, personal appearance, race, religion, or sexual identity
+and orientation.
+
+We pledge to act and interact in ways that contribute to an open, welcoming,
+diverse, inclusive, and healthy community.
+
+## Our Standards
+
+Examples of behavior that contributes to a positive environment for our
+community include:
+
+* Demonstrating empathy and kindness toward other people
+* Being respectful of differing opinions, viewpoints, and experiences
+* Giving and gracefully accepting constructive feedback
+* Accepting responsibility and apologizing to those affected by our mistakes,
+  and learning from the experience
+* Focusing on what is best not just for us as individuals, but for the
+  overall community
+
+Examples of unacceptable behavior include:
+
+* The use of sexualized language or imagery, and sexual attention or
+  advances of any kind
+* Trolling, insulting or derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or email
+  address, without their explicit permission
+* Other conduct which could reasonably be considered inappropriate in a
+  professional setting
+
+## Enforcement Responsibilities
+
+Community leaders are responsible for clarifying and enforcing our standards of
+acceptable behavior and will take appropriate and fair corrective action in
+response to any behavior that they deem inappropriate, threatening, offensive,
+or harmful.
+
+Community leaders have the right and responsibility to remove, edit, or reject
+comments, commits, code, wiki edits, issues, and other contributions that are
+not aligned to this Code of Conduct, and will communicate reasons for moderation
+decisions when appropriate.
+
+## Scope
+
+This Code of Conduct applies within all community spaces, and also applies when
+an individual is officially representing the community in public spaces.
+Examples of representing our community include using an official e-mail address,
+posting via an official social media account, or acting as an appointed
+representative at an online or offline event.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported to the community leaders responsible for enforcement at
+support@sftpgo.com.
+All complaints will be reviewed and investigated promptly and fairly.
+
+All community leaders are obligated to respect the privacy and security of the
+reporter of any incident.
+
+## Enforcement Guidelines
+
+Community leaders will follow these Community Impact Guidelines in determining
+the consequences for any action they deem in violation of this Code of Conduct:
+
+### 1. Correction
+
+**Community Impact**: Use of inappropriate language or other behavior deemed
+unprofessional or unwelcome in the community.
+
+**Consequence**: A private, written warning from community leaders, providing
+clarity around the nature of the violation and an explanation of why the
+behavior was inappropriate. A public apology may be requested.
+
+### 2. Warning
+
+**Community Impact**: A violation through a single incident or series
+of actions.
+
+**Consequence**: A warning with consequences for continued behavior. No
+interaction with the people involved, including unsolicited interaction with
+those enforcing the Code of Conduct, for a specified period of time. This
+includes avoiding interactions in community spaces as well as external channels
+like social media. Violating these terms may lead to a temporary or
+permanent ban.
+
+### 3. Temporary Ban
+
+**Community Impact**: A serious violation of community standards, including
+sustained inappropriate behavior.
+
+**Consequence**: A temporary ban from any sort of interaction or public
+communication with the community for a specified period of time. No public or
+private interaction with the people involved, including unsolicited interaction
+with those enforcing the Code of Conduct, is allowed during this period.
+Violating these terms may lead to a permanent ban.
+
+### 4. Permanent Ban
+
+**Community Impact**: Demonstrating a pattern of violation of community
+standards, including sustained inappropriate behavior,  harassment of an
+individual, or aggression toward or disparagement of classes of individuals.
+
+**Consequence**: A permanent ban from any sort of public interaction within
+the community.
+

 want it, that you can change the software or use pieces of it in new
 free programs, and that you know you can do these things.
 
-  To protect your rights, we need to prevent others from denying you
-these rights or asking you to surrender the rights.  Therefore, you have
-certain responsibilities if you distribute copies of the software, or if
-you modify it: responsibilities to respect the freedom of others.
+  Developers that use our General Public Licenses protect your rights
+with two steps: (1) assert copyright on the software, and (2) offer
+you this License which gives you legal permission to copy, distribute
+and/or modify the software.
 
-  For example, if you distribute copies of such a program, whether
-gratis or for a fee, you must pass on to the recipients the same
-freedoms that you received.  You must make sure that they, too, receive
-or can get the source code.  And you must show them these terms so they
-know their rights.
+  A secondary benefit of defending all users' freedom is that
+improvements made in alternate versions of the program, if they
+receive widespread use, become available for other developers to
+incorporate.  Many developers of free software are heartened and
+encouraged by the resulting cooperation.  However, in the case of
+software used on network servers, this result may fail to come about.
+The GNU General Public License permits making a modified version and
+letting the public access it on a server without ever releasing its
+source code to the public.
 
-  Developers that use the GNU GPL protect your rights with two steps:
-(1) assert copyright on the software, and (2) offer you this License
-giving you legal permission to copy, distribute and/or modify it.
+  The GNU Affero General Public License is designed specifically to
+ensure that, in such cases, the modified source code becomes available
+to the community.  It requires the operator of a network server to
+provide the source code of the modified version running there to the
+users of that server.  Therefore, public use of a modified version, on
+a publicly accessible server, gives the public access to the source
+code of the modified version.
 
-  For the developers' and authors' protection, the GPL clearly explains
-that there is no warranty for this free software.  For both users' and
-authors' sake, the GPL requires that modified versions be marked as
-changed, so that their problems will not be attributed erroneously to
-authors of previous versions.
-
-  Some devices are designed to deny users access to install or run
-modified versions of the software inside them, although the manufacturer
-can do so.  This is fundamentally incompatible with the aim of
-protecting users' freedom to change the software.  The systematic
-pattern of such abuse occurs in the area of products for individuals to
-use, which is precisely where it is most unacceptable.  Therefore, we
-have designed this version of the GPL to prohibit the practice for those
-products.  If such problems arise substantially in other domains, we
-stand ready to extend this provision to those domains in future versions
-of the GPL, as needed to protect the freedom of users.
-
-  Finally, every program is threatened constantly by software patents.
-States should not allow patents to restrict development and use of
-software on general-purpose computers, but in those that do, we wish to
-avoid the special danger that patents applied to a free program could
-make it effectively proprietary.  To prevent this, the GPL assures that
-patents cannot be used to render the program non-free.
+  An older license, called the Affero General Public License and

 [![Mentioned in Awesome Go](https://awesome.re/mentioned-badge.svg)](https://github.com/avelino/awesome-go)
 
-Fully featured and highly configurable SFTP server with optional FTP/S and WebDAV support, written in Go.
-It can serve local filesystem, S3 (compatible) Object Storage, Google Cloud Storage and Azure Blob Storage.
+Full-featured and highly configurable event-driven file transfer solution.
+Server protocols: SFTP, HTTP/S, FTP/S, WebDAV.
+Storage backends: local filesystem, encrypted local filesystem, S3 (compatible) Object Storage, Google Cloud Storage, Azure Blob Storage, other SFTP servers.
 
-## Features
+With SFTPGo you can leverage local and cloud storage backends for exchanging and storing files internally or with business partners using the same tools and processes you are already familiar with.
 
-- SFTPGo uses virtual accounts stored inside a "data provider".
-- SQLite, MySQL, PostgreSQL, bbolt (key/value store in pure Go) and in-memory data providers are supported.
-- Each account is chrooted to its home directory.
-- Public key and password authentication. Multiple public keys per user are supported.
-- SSH user [certificate authentication](https://cvsweb.openbsd.org/src/usr.bin/ssh/PROTOCOL.certkeys?rev=1.8).
-- Keyboard interactive authentication. You can easily setup a customizable multi-factor authentication.
-- Partial authentication. You can configure multi-step authentication requiring, for example, the user password after successful public key authentication.
-- Per user authentication methods. You can configure the allowed authentication methods for each user.
-- Custom authentication via external programs/HTTP API is supported.
-- Dynamic user modification before login via external programs/HTTP API is supported.
-- Quota support: accounts can have individual quota expressed as max total size and/or max number of files.
-- Bandwidth throttling is supported, with distinct settings for upload and download.
-- Per user maximum concurrent sessions.
-- Per user and per directory permission management: list directory contents, upload, overwrite, download, delete, rename, create directories, create symlinks, change owner/group and mode, change access and modification times.
-- Per user files/folders ownership mapping: you can map all the users to the system account that runs SFTPGo (all platforms are supported) or you can run SFTPGo as root user and map each user or group of users to a different system account (\*NIX only).
-- Per user IP filters are supported: login can be restricted to specific ranges of IP addresses or to a specific IP address.
-- Per user and per directory file extensions filters are supported: files can be allowed or denied based on their extensions.
-- Virtual folders are supported: directories outside the user home directory can be exposed as virtual folders.
-- Configurable custom commands and/or HTTP notifications on file upload, download, pre-delete, delete, rename, on SSH commands and on user add, update and delete.
-- Automatically terminating idle connections.
-- Atomic uploads are configurable.
-- Support for Git repositories over SSH.
-- SCP and rsync are supported.
-- FTP/S is supported. You can configure the FTP service to require TLS for both control and data connections.
-- [WebDAV](./docs/webdav.md) is supported.
-- Support for serving local filesystem, S3 Compatible Object Storage and Google Cloud Storage over SFTP/SCP/FTP/WebDAV.
-- Per user protocols restrictions. You can configure the allowed protocols (SSH/FTP/WebDAV) for each user.
-- [Prometheus metrics](./docs/metrics.md) are exposed.
-- Support for HAProxy PROXY protocol: you can proxy and/or load balance the SFTP/SCP/FTP/WebDAV service without losing the information about the client's address.
-- [REST API](./docs/rest-api.md) for users and folders management, backup, restore and real time reports of the active connections with possibility of forcibly closing a connection.
-- [Web based administration interface](./docs/web-admin.md) to easily manage users, folders and connections.
-- Easy [migration](./examples/rest-api-cli#convert-users-from-other-stores) from Linux system user accounts.
-- [Portable mode](./docs/portable-mode.md): a convenient way to share a single directory on demand.
-- [SFTP subsystem mode](./docs/sftp-subsystem.md): you can use SFTPGo as OpenSSH's SFTP subsystem.
-- Performance analysis using built-in [profiler](./docs/profiling.md).
-- Configuration format is at your choice: JSON, TOML, YAML, HCL, envfile are supported.
-- Log files are accurate and they are saved in the easily parsable JSON format ([more information](./docs/logs.md)).
+The WebAdmin UI allows to easily create and manage your users, folders, groups and other resources.
 
-## Platforms
+The WebClient UI allows end users to change their credentials, browse and manage their files in the browser and setup two-factor authentication which works with Microsoft Authenticator, Google Authenticator, Authy and other compatible apps.
 
-SFTPGo is developed and tested on Linux. After each commit, the code is automatically built and tested on Linux, macOS and Windows using a [GitHub Action](./.github/workflows/development.yml). The test cases are regularly manually executed and passed on FreeBSD. Other *BSD variants should work too.
+## Sponsors
 
-## Requirements
+We strongly believe in Open Source software model, so we decided to make SFTPGo available to everyone, but maintaining and evolving SFTPGo takes a lot of time and work. To make development and maintenance sustainable you should consider to support the project with a [sponsorship](https://github.com/sponsors/drakkan).
 
-- Go 1.14 or higher as build only dependency.
-- A suitable SQL server to use as data provider: PostgreSQL 9.4+ or MySQL 5.6+ or SQLite 3.x.
-- The SQL server is optional: you can choose to use an embedded bolt database as key/value store or an in memory data provider.
+We also provide [professional services](https://sftpgo.com/#pricing) to support you in using SFTPGo to the fullest.
 
-## Installation
+The open source license grant you freedom but not assurance of help. So why would you rely on free software without support or any guarantee it will stay healthy and maintained for the upcoming years?
 
-Binary releases for Linux, macOS, and Windows are available. Please visit the [releases](https://github.com/drakkan/sftpgo/releases "releases") page.
+Supporting the project benefit businesses and the community because if the project is financially sustainable, using this business model, we don't have to restrict features and/or switch to an [Open-core](https://en.wikipedia.org/wiki/Open-core_model) model. The technology stays truly open source. Everyone wins.
 
-An official Docker image is available. Documentation is [here](./docker/README.md).
+It is important to understand that you should support SFTPGo and any other Open Source project you rely on for ongoing maintenance, even if you don't have any questions or need new features, to mitigate the business risk of a project you depend on going unmaintained, with its security and development velocity implications.
 
-Some Linux distro packages are available:
+### Thank you to our sponsors
 
-- For Arch Linux via AUR:
-  - [sftpgo](https://aur.archlinux.org/packages/sftpgo/). This package follows stable releases. It requires `git`, `gcc` and `go` to build.
-  - [sftpgo-bin](https://aur.archlinux.org/packages/sftpgo-bin/). This package follows stable releases downloading the prebuilt linux binary from GitHub. It does not require `git`, `gcc` and `go` to build.
-  - [sftpgo-git](https://aur.archlinux.org/packages/sftpgo-git/). This package builds and installs the latest git master. It requires `git`, `gcc` and `go` to build.
-- Deb and RPM packages are built after each commit and for each release.
-- For Ubuntu a PPA is available [here](https://launchpad.net/~sftpgo/+archive/ubuntu/sftpgo).

-To start SFTPGo with the default settings, simply run:
+## Support policy
 
-```bash
-sftpgo serve
-```
+You can use SFTPGo for free, respecting the obligations of the Open Source license, but please do not ask or expect free support as well.
 
-Check out [this documentation](./docs/service.md) if you want to run SFTPGo as a service.
+Use [discussions](https://github.com/drakkan/sftpgo/discussions) to ask questions and get support from the community.
 
-### Data provider initialization and update
+If you report an invalid issue and/or ask for step-by-step support, your issue will be closed as invalid without further explanation and/or the "support request" label will be added. Invalid bug reports may confuse other users. Thanks for understanding.
 
-Before starting the SFTPGo server please ensure that the configured data provider is properly initialized/updated.
+## Documentation
 
-SQL based data providers (SQLite, MySQL, PostgreSQL) require the creation of a database containing the required tables. Memory and bolt data providers do not require an initialization but they could require an update to the existing data after upgrading SFTPGo.
-
-For PostgreSQL and MySQL providers, you need to create the configured database.
-
-SFTPGo will attempt to automatically detect if the data provider is initialized/updated and if not, will attempt to initialize/ update it on startup as needed.
-
-Alternately, you can create/update the required data provider structures yourself using the `initprovider` command.
-
-For example, you can simply execute the following command from the configuration directory:
-
-```bash
-sftpgo initprovider
-```
-
-Take a look at the CLI usage to learn how to specify a different configuration file:
-
-```bash
-sftpgo initprovider --help
-```
-
-You can disable automatic data provider checks/updates at startup by setting the `update_mode` configuration key to `1`.
-
-## Users and folders management
-
-After starting SFTPGo you can manage users and folders using:
-
-- the [web based administration interface](./docs/web-admin.md)
-- the [REST API](./docs/rest-api.md)
-- the sample [REST API CLI](./examples/rest-api-cli)
-
-To support embedded data providers like `bolt` and `SQLite` we can't have a CLI that directly write users and folders to the data provider, we always have to use the REST API.
-
-## Tutorials
-
-Some step-to-step tutorials can be found inside the source tree [howto](./docs/howto "How-to") directory.
-
-## Authentication options
-
-### External Authentication
-
-Custom authentication methods can easily be added. SFTPGo supports external authentication modules, and writing a new backend can be as simple as a few lines of shell script. More information can be found [here](./docs/external-auth.md).
-
-### Keyboard Interactive Authentication
-
-Keyboard interactive authentication is, in general, a series of questions asked by the server with responses provided by the client.
-This authentication method is typically used for multi-factor authentication.
-
-More information can be found [here](./docs/keyboard-interactive.md).
-
-## Dynamic user creation or modification
-
-A user can be created or modified by an external program just before the login. More information about this can be found [here](./docs/dynamic-user-mod.md).
-
-## Custom Actions
-
-SFTPGo allows to configure custom commands and/or HTTP notifications on file upload, download, delete, rename, on SSH commands and on user add, update and delete.
-
-More information about custom actions can be found [here](./docs/custom-actions.md).
-
-## Virtual folders
-
-Directories outside the user home directory can be exposed as virtual folders, more information [here](./docs/virtual-folders.md).
-
-## Other hooks
-
-You can get notified as soon as a new connection is established using the [Post-connect hook](./docs/post-connect-hook.md) and after each login using the [Post-login hook](./docs/post-login-hook.md).
-You can use your own hook to [check passwords](./docs/check-password-hook.md).
-
-## Storage backends
-
-### S3 Compatible Object Storage backends
-
-Each user can be mapped to the whole bucket or to a bucket virtual folder. This way, the mapped bucket/virtual folder is exposed over SFTP/SCP/FTP/WebDAV. More information about S3 integration can be found [here](./docs/s3.md).
-
-### Google Cloud Storage backend
-
-Each user can be mapped with a Google Cloud Storage bucket or a bucket virtual folder. This way, the mapped bucket/virtual folder is exposed over SFTP/SCP/FTP/WebDAV. More information about Google Cloud Storage integration can be found [here](./docs/google-cloud-storage.md).
-
-### Azure Blob Storage backend
-
-Each user can be mapped with an Azure Blob Storage container or a container virtual folder. This way, the mapped container/virtual folder is exposed over SFTP/SCP/FTP/WebDAV. More information about Azure Blob Storage integration can be found [here](./docs/azure-blob-storage.md).
-
-### Other Storage backends
-
-Adding new storage backends is quite easy:
-
-- implement the [Fs interface](./vfs/vfs.go#L18 "interface for filesystem backends").
-- update the user method `GetFilesystem` to return the new backend
-- update the web interface and the REST API CLI
-- add the flags for the new storage backed to the `portable` mode
-
-Anyway, some backends require a pay per use account (or they offer free account for a limited time period only). To be able to add support for such backends or to review pull requests, please provide a test account. The test account must be available for enough time to be able to maintain the backend and do basic tests before each new release.
-
-## Brute force protection
-
-The [connection failed logs](./docs/logs.md) can be used for integration in tools such as [Fail2ban](http://www.fail2ban.org/). Example of [jails](./fail2ban/jails) and [filters](./fail2ban/filters) working with `systemd`/`journald` are available in fail2ban directory.
-
-## Account's configuration properties
-
-Details information about account configuration properties can be found [here](./docs/account.md).
-
-## Performance
-
-SFTPGo can easily saturate a Gigabit connection on low end hardware with no special configuration, this is generally enough for most use cases.
-
-More in-depth analysis of performance can be found [here](./docs/performance.md).
+You can read more about supported features and documentation at [sftpgo.github.io](https://sftpgo.github.io/).
 
 ## Release Cadence
 
-SFTPGo releases are feature-driven, we don't have a fixed time based schedule. As a rough estimate, you can expect 1 or 2 new releases per year.

-# Official Docker image
-
-SFTPGo provides an official Docker image, it is available on both [Docker Hub](https://hub.docker.com/r/drakkan/sftpgo) and on [GitHub Container Registry](https://github.com/users/drakkan/packages/container/package/sftpgo).
-
-## Supported tags and respective Dockerfile links
-
-- [v1.2.0, v1.2, v1, latest](https://github.com/drakkan/sftpgo/blob/v1.2.0/Dockerfile)
-- [v1.2.0-alpine, v1.2-alpine, v1-alpine, alpine](https://github.com/drakkan/sftpgo/blob/v1.2.0/Dockerfile.alpine)
-- [edge](../Dockerfile)
-- [edge-alpine](../Dockerfile.alpine)
-
-## How to use the SFTPGo image
-
-### Start a `sftpgo` server instance
-
-Starting a SFTPGo instance is simple:
-
-```shell
-docker run --name some-sftpgo -p 127.0.0.1:8080:8080 -p 2022:2022 -d "drakkan/sftpgo:tag"
-```
-
-... where `some-sftpgo` is the name you want to assign to your container, and `tag` is the tag specifying the SFTPGo version you want. See the list above for relevant tags.
-
-Now visit [http://localhost:8080/](http://localhost:8080/) and create a new SFTPGo user. The SFTP service is available on port 2022.
-
-If you prefer GitHub Container Registry to Docker Hub replace `drakkan/sftpgo:tag` with `ghcr.io/drakkan/sftpgo:tag`.
-
-### Container shell access and viewing SFTPGo logs
-
-The docker exec command allows you to run commands inside a Docker container. The following command line will give you a bash shell inside your `sftpgo` container:
-
-```shell
-docker exec -it some-sftpgo bash
-```
-
-The logs are available through Docker's container log:
-
-```shell
-docker logs some-sftpgo
-```
-
-### Where to Store Data
-
-Important note: There are several ways to store data used by applications that run in Docker containers. We encourage users of the SFTPGo images to familiarize themselves with the options available, including:
-
-- Let Docker manage the storage for SFTPGo data by [writing them to disk on the host system using its own internal volume management](https://docs.docker.com/engine/tutorials/dockervolumes/#adding-a-data-volume). This is the default and is easy and fairly transparent to the user. The downside is that the files may be hard to locate for tools and applications that run directly on the host system, i.e. outside containers.
-- Create a data directory on the host system (outside the container) and [mount this to a directory visible from inside the container]((https://docs.docker.com/engine/tutorials/dockervolumes/#mount-a-host-directory-as-a-data-volume)). This places the SFTPGo files in a known location on the host system, and makes it easy for tools and applications on the host system to access the files. The downside is that the user needs to make sure that the directory exists, and that e.g. directory permissions and other security mechanisms on the host system are set up correctly. The SFTPGo image runs using `1000` as UID/GID by default.
-
-The Docker documentation is a good starting point for understanding the different storage options and variations, and there are multiple blogs and forum postings that discuss and give advice in this area. We will simply show the basic procedure here for the latter option above:
-
-1. Create a data directory on a suitable volume on your host system, e.g. `/my/own/sftpgodata`.
-2. Create a home directory for the sftpgo container user on your host system e.g. `/my/own/sftpgohome`.
-3. Start your SFTPGo container like this:
-
-```shell
-docker run --name some-sftpgo \
-    -p 127.0.0.1:8080:8090 \
-    -p 2022:2022 \
-    --mount type=bind,source=/my/own/sftpgodata,target=/srv/sftpgo \
-    --mount type=bind,source=/my/own/sftpgohome,target=/var/lib/sftpgo \
-    -e SFTPGO_HTTPD__BIND_PORT=8090 \
-    -d "drakkan/sftpgo:tag"
-```
-
-As you can see SFTPGo uses two volumes:
-
-- `/srv/sftpgo` to handle persistent data. The default home directory for SFTP/FTP/WebDAV users is `/srv/sftpgo/data/<username>`. Backups are stored in `/srv/sftpgo/backups`
-- `/var/lib/sftpgo` is the home directory for the sftpgo system user defined inside the container. This is the container working directory too, host keys will be created here when using the default configuration.
-
-### Configuration
-
-The runtime configuration can be customized via environment variables that you can set passing the `-e` option to the `docker run` command or inside the `environment` section if you are using [docker stack deploy](https://docs.docker.com/engine/reference/commandline/stack_deploy/) or [docker-compose](https://github.com/docker/compose).
-
-Please take a look [here](../docs/full-configuration.md#environment-variables) to learn how to configure SFTPGo via environment variables.
-
-Alternately you can mount your custom configuration file to `/var/lib/sftpgo` or `/var/lib/sftpgo/.config/sftpgo`.
-
-### Running as an arbitrary user
-
-The SFTPGo image runs using `1000` as UID/GID by default. If you know the permissions of your data and/or configuration directory are already set appropriately or you have need of running SFTPGo with a specific UID/GID, it is possible to invoke this image with `--user` set to any value (other than `root/0`) in order to achieve the desired access/configuration:
-
-```shell
-$ ls -lnd data
-drwxr-xr-x 2 1100 11000 6  6 nov 09.09 data
-$ ls -lnd config
-drwxr-xr-x 2 1100 11000 6  6 nov 09.19 config
-```
-
-With the above directory permissions, you can start a SFTPGo instance like this:
-
-```shell
-docker run --name some-sftpgo \
-    --user 1100:1100 \
-    -p 127.0.0.1:8080:8080 \
-    -p 2022:2022 \
-    --mount type=bind,source="${PWD}/data",target=/srv/sftpgo \
-    --mount type=bind,source="${PWD}/config",target=/var/lib/sftpgo \
-    -d "drakkan/sftpgo:tag"
-```
-
-## Image Variants
-
-The `sftpgo` images comes in many flavors, each designed for a specific use case. The `edge` and `edge-alpine`tags are updated after each new commit.
-
-### `sftpgo:<version>`
-
-This is the defacto image, it is based on [Debian](https://www.debian.org/), available in [the `debian` official image](https://hub.docker.com/_/debian). If you are unsure about what your needs are, you probably want to use this one.
-
-### `sftpgo:<version>-alpine`
-
-This image is based on the popular [Alpine Linux project](https://alpinelinux.org/), available in [the `alpine` official image](https://hub.docker.com/_/alpine). Alpine Linux is much smaller than most distribution base images (~5MB), and thus leads to much slimmer images in general.
-
-This variant is highly recommended when final image size being as small as possible is desired. The main caveat to note is that it does use [musl libc](https://musl.libc.org/) instead of [glibc and friends](https://www.etalabs.net/compare_libcs.html), so certain software might run into issues depending on the depth of their libc requirements. However, most software doesn't have an issue with this, so this variant is usually a very safe choice. See [this Hacker News comment thread](https://news.ycombinator.com/item?id=10782897) for more discussion of the issues that might arise and some pro/con comparisons of using Alpine-based images.
-
-## Helm Chart
-
-An helm chart is [available](https://artifacthub.io/packages/helm/sagikazarmark/sftpgo). You can find the source code [here](https://github.com/sagikazarmark/helm-charts/tree/master/charts/sftpgo).

-# SFTPGo with Docker and Alpine
-
-:warning: The recommended way to run SFTPGo on Docker is to use the official [images](https://hub.docker.com/r/drakkan/sftpgo). The documentation here is now obsolete.
-
-This DockerFile is made to build image to host multiple instances of SFTPGo started with different users.
-
-## Example
-
-> 1003 is a custom uid:gid for this instance of SFTPGo
-
-```bash
-# Prereq on docker host
-sudo groupadd -g 1003 sftpgrp && \
-  sudo useradd -u 1003 -g 1003 sftpuser -d /home/sftpuser/ && \
-  sudo -u sftpuser mkdir /home/sftpuser/{conf,data} && \
-  curl https://raw.githubusercontent.com/drakkan/sftpgo/master/sftpgo.json -o /home/sftpuser/conf/sftpgo.json
-
-# Edit sftpgo.json as you need
-
-# Get and build SFTPGo image.
-# Add --build-arg TAG=LATEST to build the latest tag or e.g. TAG=v1.0.0 for a specific tag/commit.
-# Add --build-arg FEATURES=<build features comma separated> to specify the features to build.
-git clone https://github.com/drakkan/sftpgo.git && \
-  cd sftpgo && \
-  sudo docker build -t sftpgo docker/sftpgo/alpine/
-
-# Initialize the configured provider. For PostgreSQL and MySQL providers you need to create the configured database and the "initprovider" command will create the required tables.
-sudo docker run --name sftpgo \
-  -e PUID=1003 \
-  -e GUID=1003 \
-  -v /home/sftpuser/conf/:/srv/sftpgo/config \
-  sftpgo initprovider -c /srv/sftpgo/config
-
-# Start the image
-sudo docker rm sftpgo && sudo docker run --name sftpgo \
-  -e SFTPGO_LOG_FILE_PATH= \
-  -e SFTPGO_CONFIG_DIR=/srv/sftpgo/config \
-  -e SFTPGO_HTTPD__TEMPLATES_PATH=/srv/sftpgo/web/templates \

-  -v /home/sftpuser/data:/data \
-  -v /home/sftpuser/backups:/srv/sftpgo/backups \
-  sftpgo
-```
-
-If you want to enable FTP/S you also need the publish the FTP port and the FTP passive port range, defined in your `Dockerfile`, by adding, for example, the following options to the `docker run` command `-p 2121:2121 -p 50000-50100:50000-50100`. The same goes for WebDAV, you need to publish the configured port.
-
-The script `entrypoint.sh` makes sure to correct the permissions of directories and start the process with the right user.
-
-Several images can be run with different parameters.
-
-## Custom systemd script
-
-An example of systemd script is present [here](sftpgo.service), with `Environment` parameter to set `PUID` and `GUID`
-
-`WorkingDirectory` parameter must be exist with one file in this directory like `sftpgo-${PUID}.env` corresponding to the variable file for SFTPGo instance.

-# Dockerfile based on Debian stable
-
-:warning: The recommended way to run SFTPGo on Docker is to use the official [images](https://hub.docker.com/r/drakkan/sftpgo). The documentation here is now obsolete.
-
-Please read the comments inside the `Dockerfile` to learn how to customize things for your setup.
-
-You can build the container image using `docker build`, for example:
-
-```bash
-docker build -t="drakkan/sftpgo" .
-```
-
-This will build master of github.com/drakkan/sftpgo.
-
-To build the latest tag you can add `--build-arg TAG=LATEST` and to build a specific tag/commit you can use for example `TAG=v1.0.0`, like this:
-
-```bash
-docker build -t="drakkan/sftpgo" --build-arg TAG=v1.0.0 .
-```
-
-To specify the features to build you can add `--build-arg FEATURES=<build features comma separated>`. For example you can disable SQLite and S3 support like this:
-
-```bash
-docker build -t="drakkan/sftpgo" --build-arg FEATURES=nosqlite,nos3 .
-```
-
-Please take a look at the [build from source](./../../../docs/build-from-source.md) documentation for the complete list of the features that can be disabled.
-
-Now create the required folders on the host system, for example:
-
-```bash
-sudo mkdir -p /srv/sftpgo/data /srv/sftpgo/config /srv/sftpgo/backups
-```
-
-and give write access to them to the UID/GID defined inside the `Dockerfile`. You can choose to create a new user, on the host system, with a matching UID/GID pair, or simply do something like this:
-
-```bash
-sudo chown -R <UID>:<GID> /srv/sftpgo/data /srv/sftpgo/config /srv/sftpgo/backups
-```
-
-Download the default configuration file and edit it as you need:
-
-```bash
-sudo curl https://raw.githubusercontent.com/drakkan/sftpgo/master/sftpgo.json -o /srv/sftpgo/config/sftpgo.json
-```
-
-Initialize the configured provider. For PostgreSQL and MySQL providers you need to create the configured database and the `initprovider` command will create the required tables:
-
-```bash
-docker run --name sftpgo --mount type=bind,source=/srv/sftpgo/config,target=/app/config drakkan/sftpgo initprovider -c /app/config
-```
-
-and finally you can run the image using something like this:
-
-```bash
-docker rm sftpgo && docker run --name sftpgo -p 8080:8080 -p 2022:2022 --mount type=bind,source=/srv/sftpgo/data,target=/app/data --mount type=bind,source=/srv/sftpgo/config,target=/app/config --mount type=bind,source=/srv/sftpgo/backups,target=/app/backups drakkan/sftpgo
-```
-
-If you want to enable FTP/S you also need the publish the FTP port and the FTP passive port range, defined in your `Dockerfile`, by adding, for example, the following options to the `docker run` command `-p 2121:2121 -p 50000-50100:50000-50100`. The same goes for WebDAV, you need to publish the configured port.

-# Account's configuration properties
-
-For each account, the following properties can be configured:
-
-- `username`
-- `password` used for password authentication. For users created using SFTPGo REST API, if the password has no known hashing algo prefix, it will be stored using argon2id. SFTPGo supports checking passwords stored with bcrypt, pbkdf2, md5crypt and sha512crypt too. For pbkdf2 the supported format is `$<algo>$<iterations>$<salt>$<hashed pwd base64 encoded>`, where algo is `pbkdf2-sha1` or `pbkdf2-sha256` or `pbkdf2-sha512` or `$pbkdf2-b64salt-sha256$`. For example the `pbkdf2-sha256` of the word `password` using 150000 iterations and `E86a9YMX3zC7` as salt must be stored as `$pbkdf2-sha256$150000$E86a9YMX3zC7$R5J62hsSq+pYw00hLLPKBbcGXmq7fj5+/M0IFoYtZbo=`. In pbkdf2 variant with `b64salt` the salt is base64 encoded. For bcrypt the format must be the one supported by golang's [crypto/bcrypt](https://godoc.org/golang.org/x/crypto/bcrypt) package, for example the password `secret` with cost `14` must be stored as `$2a$14$ajq8Q7fbtFRQvXpdCq7Jcuy.Rx1h/L4J60Otx.gyNLbAYctGMJ9tK`. For md5crypt and sha512crypt we support the format used in `/etc/shadow` with the `$1$` and `$6$` prefix, this is useful if you are migrating from Unix system user accounts. We support Apache md5crypt (`$apr1$` prefix) too. Using the REST API you can send a password hashed as bcrypt, pbkdf2, md5crypt or sha512crypt and it will be stored as is.
-- `public_keys` array of public keys. At least one public key or the password is mandatory.
-- `status` 1 means "active", 0 "inactive". An inactive account cannot login.
-- `expiration_date` expiration date as unix timestamp in milliseconds. An expired account cannot login. 0 means no expiration.
-- `home_dir` the user cannot upload or download files outside this directory. Must be an absolute path. A local home directory is required for Cloud Storage Backends too: in this case it will store temporary files.
-- `virtual_folders` list of mappings between virtual SFTP/SCP paths and local filesystem paths outside the user home directory. More information can be found [here](./virtual-folders.md)
-- `uid`, `gid`. If SFTPGo runs as root system user then the created files and directories will be assigned to this system uid/gid. Ignored on windows or if SFTPGo runs as non root user: in this case files and directories for all SFTP users will be owned by the system user that runs SFTPGo.
-- `max_sessions` maximum concurrent sessions. 0 means unlimited.
-- `quota_size` maximum size allowed as bytes. 0 means unlimited.
-- `quota_files` maximum number of files allowed. 0 means unlimited.
-- `permissions` for SFTP paths. The following per directory permissions are supported:
-  - `*` all permissions are granted
-  - `list` list items is allowed
-  - `download` download files is allowed
-  - `upload` upload files is allowed
-  - `overwrite` overwrite an existing file, while uploading, is allowed. `upload` permission is required to allow file overwrite
-  - `delete` delete files or directories is allowed
-  - `rename` rename a file or a directory is allowed if this permission is granted on source and target path. You can enable rename in a more controlled way granting `delete` permission on source directory and `upload`/`create_dirs`/`create_symlinks` permissions on target directory
-  - `create_dirs` create directories is allowed
-  - `create_symlinks` create symbolic links is allowed
-  - `chmod` changing file or directory permissions is allowed. On Windows, only the 0200 bit (owner writable) of mode is used; it controls whether the file's read-only attribute is set or cleared. The other bits are currently unused. Use mode 0400 for a read-only file and 0600 for a readable+writable file.
-  - `chown` changing file or directory owner and group is allowed. Changing owner and group is not supported on Windows.
-  - `chtimes` changing file or directory access and modification time is allowed
-- `upload_bandwidth` maximum upload bandwidth as KB/s, 0 means unlimited.
-- `download_bandwidth` maximum download bandwidth as KB/s, 0 means unlimited.
-- `allowed_ip`, List of IP/Mask allowed to login. Any IP address not contained in this list cannot login. IP/Mask must be in CIDR notation as defined in RFC 4632 and RFC 4291, for example "192.0.2.0/24" or "2001:db8::/32"
-- `denied_ip`, List of IP/Mask not allowed to login. If an IP address is both allowed and denied then login will be denied
-- `max_upload_file_size`, max allowed size, as bytes, for a single file upload. The upload will be aborted if/when the size of the file being sent exceeds this limit. 0 means unlimited. This restriction does not apply for SSH system commands such as `git` and `rsync`
-- `denied_login_methods`, List of login methods not allowed. To enable multi-step authentication you have to allow only multi-step login methods. If password login method is denied or no password is set then FTP and WebDAV users cannot login. The following login methods are supported:
-  - `publickey`
-  - `password`
-  - `keyboard-interactive`
-  - `publickey+password`
-  - `publickey+keyboard-interactive`
-- `denied_protocols`, list of protocols not allowed. The following protocols are supported:
-  - `SSH`
-  - `FTP`
-  - `DAV`
-- `file_extensions`, list of struct. These restrictions do not apply to files listing for performance reasons, so a denied file cannot be downloaded/overwritten/renamed but it will still be listed in the list of files. Please note that these restrictions can be easily bypassed. Each struct contains the following fields:
-  - `allowed_extensions`, list of, case insensitive, allowed files extension. Shell like expansion is not supported so you have to specify `.jpg` and not `*.jpg`. Any file that does not end with this suffix will be denied
-  - `denied_extensions`, list of, case insensitive, denied files extension. Denied file extensions are evaluated before the allowed ones
-  - `path`, SFTP/SCP path, if no other specific filter is defined, the filter apply for sub directories too. For example if filters are defined for the paths `/` and `/sub` then the filters for `/` are applied for any file outside the `/sub` directory
-- `fs_provider`, filesystem to serve via SFTP. Local filesystem (0), S3 Compatible Object Storage (1), Google Cloud Storage (2) and Azure Blob Storage (3) are supported
-- `s3_bucket`, required for S3 filesystem
-- `s3_region`, required for S3 filesystem. Must match the region for your bucket. You can find here the list of available [AWS regions](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/using-regions-availability-zones.html#concepts-available-regions). For example if your bucket is at `Frankfurt` you have to set the region to `eu-central-1`
-- `s3_access_key`
-- `s3_access_secret`, if provided it is stored encrypted (AES-256-GCM). You can leave access key and access secret blank to use credentials from environment
-- `s3_endpoint`, specifies a S3 endpoint (server) different from AWS. It is not required if you are connecting to AWS
-- `s3_storage_class`, leave blank to use the default or specify a valid AWS [storage class](https://docs.aws.amazon.com/AmazonS3/latest/dev/storage-class-intro.html)
-- `s3_key_prefix`, allows to restrict access to the folder identified by this prefix and its contents
-- `s3_upload_part_size`, the buffer size for multipart uploads (MB). Zero means the default (5 MB). Minimum is 5
-- `s3_upload_concurrency` how many parts are uploaded in parallel
-- `gcs_bucket`, required for GCS filesystem
-- `gcs_credentials`, Google Cloud Storage JSON credentials base64 encoded
-- `gcs_automatic_credentials`, integer. Set to 1 to use Application Default Credentials strategy or set to 0 to use explicit credentials via `gcs_credentials`
-- `gcs_storage_class`
-- `gcs_key_prefix`, allows to restrict access to the folder identified by this prefix and its contents
-- `az_container`, Azure Blob Storage container
-- `az_account_name`, Azure account name. leave blank to use SAS URL
-- `az_account_key`, Azure account key. leave blank to use SAS URL. If provided it is stored encrypted (AES-256-GCM)
-- `az_sas_url`, Azure shared access signature URL
-- `az_endpoint`, Default is "blob.core.windows.net". If you use the emulator the endpoint must include the protocol, for example "http://127.0.0.1:10000"
-- `az_upload_part_size`, the buffer size for multipart uploads (MB). Zero means the default (4 MB)
-- `az_upload_concurrency`,  how many parts are uploaded in parallel. Zero means the default (2)
-- `az_key_prefix`,  allows to restrict access to the folder identified by this prefix and its contents
-- `az_use_emulator`, boolean
-
-These properties are stored inside the data provider.
-
-If you want to use your existing accounts, you have these options:
-
-- you can import your users inside SFTPGo. Take a look at [sftpgo_api_cli](../examples/rest-api-cli#convert-users-from-other-stores "SFTPGo API CLI example"), it can convert and import users from Linux system users and Pure-FTPd/ProFTPD virtual users
-- you can use an external authentication program
-
-Please take a look at the [OpenAPI schema](../httpd/schema/openapi.yaml) for the exact definitions of user and folder fields.
-If you need an example you can export a dump using the REST API CLI client or by invoking the `dumpdata` endpoint directly, for example:
-
-```shell
-curl "http://127.0.0.1:8080/api/v1/dumpdata?output_file=dump.json&indent=1"
-```
-
-the dump is a JSON with users and folder.

-# Azure Blob Storage backend
-
-To connect SFTPGo to Azure Blob Storage, you need to specify the access credentials. Azure Blob Storage has different options for credentials, we support:
-
-1. Providing an account name and account key.
-2. Providing a shared access signature (SAS).
-
-If you authenticate using account and key you also need to specify a container. The endpoint can generally be left blank, the default is `blob.core.windows.net`.
-
-If you provide a SAS URL the container is optional and if given it must match the one inside the shared access signature.
-
-If you want to connect to an emulator such as [Azurite](https://github.com/Azure/Azurite) you need to provide the account name/key pair and an endpoint prefixed with the protocol, for example `http://127.0.0.1:10000`.
-
-Specifying a different `key_prefix`, you can assign different "folders" of the same container to different users. This is similar to a chroot directory for local filesystem. Each SFTPGo user can only access the assigned folder and its contents. The folder identified by `key_prefix` does not need to be pre-created.
-
-For multipart uploads you can customize the parts size and the upload concurrency. Please note that if the upload bandwidth between the client and SFTPGo is greater than the upload bandwidth between SFTPGo and the Azure Blob service then the client should wait for the last parts to be uploaded to Azure after finishing uploading the file to SFTPGo, and it may time out. Keep this in mind if you customize these parameters.
-
-The configured container must exist.
-
-This backend is very similar to the [S3](./s3.md) backend, and it has the same limitations.

-# Check password hook
-
-This hook allows you to externally check the provided password, its main use case is to allow to easily support things like password+OTP for protocols without keyboard interactive support such as FTP and WebDAV. You can ask your users to login using a string consisting of a fixed password and a One Time Token, you can verify the token inside the hook and ask to SFTPGo to verify the fixed part.
-
-The same thing can be achieved using [External authentication](./external-auth.md) but using this hook is simpler in some use cases.
-
-The `check password hook` can be defined as the absolute path of your program or an HTTP URL.
-
-The expected response is a JSON serialized struct containing the following keys:
-
-- `status` integer. 0 means KO, 1 means OK, 2 means partial success
-- `to_verify` string. For `status` = 2 SFTPGo will check this password against the one stored inside SFTPGo data provider
-
-If the hook defines an external program it can read the following environment variables:
-
-- `SFTPGO_AUTHD_USERNAME`
-- `SFTPGO_AUTHD_PASSWORD`
-- `SFTPGO_AUTHD_IP`
-- `SFTPGO_AUTHD_PROTOCOL`, possible values are `SSH`, `FTP`, `DAV`
-
-Previous global environment variables aren't cleared when the script is called. The content of these variables is _not_ quoted. They may contain special characters. They are under the control of a possibly malicious remote user.
-
-The program must write, on its standard output, the expected JSON serialized response described above.
-
-If the hook is an HTTP URL then it will be invoked as HTTP POST. The request body will contain a JSON serialized struct with the following fields:
-
-- `username`
-- `password`
-- `ip`
-- `protocol`, possible values are `SSH`, `FTP`, `DAV`
-
-If authentication succeeds the HTTP response code must be 200 and the response body must contain the expected JSON serialized response described above.
-
-The program hook must finish within 30 seconds, the HTTP hook timeout will use the global configuration for HTTP clients.
-
-You can also restrict the hook scope using the `check_password_scope` configuration key:
-
-- `0` means all supported protocols.
-- `1` means SSH only
-- `2` means FTP only
-- `4` means WebDAV only
-
-You can combine the scopes. For example, 6 means FTP and WebDAV.
-
-An example check password program allowing 2FA using password + one time token can be found inside the source tree [checkpwd](../examples/OTP/authy/checkpwd) directory.

-# Custom Actions
-
-The `actions` struct inside the "common" configuration section allows to configure the actions for file operations and SSH commands.
-The `hook` can be defined as the absolute path of your program or an HTTP URL.
-
-The `upload` condition includes both uploads to new files and overwrite of existing files. If an upload is aborted for quota limits SFTPGo tries to remove the partial file, so if the notification reports a zero size file and a quota exceeded error the file has been deleted. The `ssh_cmd` condition will be triggered after a command is successfully executed via SSH. `scp` will trigger the `download` and `upload` conditions and not `ssh_cmd`.
-The notification will indicate if an error is detected and so, for example, a partial file is uploaded.
-The `pre-delete` action, if defined, will be called just before files deletion. If the external command completes with a zero exit status or the HTTP notification response code is `200` then SFTPGo will assume that the file was already deleted/moved and so it will not try to remove the file and it will not execute the hook defined for the `delete` action.
-
-If the `hook` defines a path to an external program, then this program is invoked with the following arguments:
-
-- `action`, string, possible values are: `download`, `upload`, `pre-delete`,`delete`, `rename`, `ssh_cmd`
-- `username`
-- `path` is the full filesystem path, can be empty for some ssh commands
-- `target_path`, non-empty for `rename` action and for `sftpgo-copy` SSH command

-# Dynamic user creation or modification
-
-Dynamic user creation or modification is supported via an external program or an HTTP URL that can be invoked just before the user login.
-To enable dynamic user modification, you must set the absolute path of your program or an HTTP URL using the `pre_login_hook` key in your configuration file.
-
-The external program can read the following environment variables to get info about the user trying to login:
-
-- `SFTPGO_LOGIND_USER`, it contains the user trying to login serialized as JSON. A JSON serialized user id equal to zero means the user does not exist inside SFTPGo
-- `SFTPGO_LOGIND_METHOD`, possible values are: `password`, `publickey` and `keyboard-interactive`
-- `SFTPGO_LOGIND_IP`, ip address of the user trying to login
-- `SFTPGO_LOGIND_PROTOCOL`, possible values are `SSH`, `FTP`, `DAV`
-
-The program must write, on its standard output:
-
-- an empty string (or no response at all) if the user should not be created/updated
-- or the SFTPGo user, JSON serialized, if you want to create or update the given user
-
-If the hook is an HTTP URL then it will be invoked as HTTP POST. The login method, the used protocol and the ip address of the user trying to login are added to the query string, for example `<http_url>?login_method=password&ip=1.2.3.4&protocol=SSH`.
-The request body will contain the user trying to login serialized as JSON. If no modification is needed the HTTP response code must be 204, otherwise the response code must be 200 and the response body a valid SFTPGo user serialized as JSON.
-
-Actions defined for user's updates will not be executed in this case and an already logged in user with the same username will not be disconnected, you have to handle these things yourself.
-
-The JSON response can include only the fields to update instead of the full user. For example, if you want to disable the user, you can return a response like this:
-
-```json
-{"status": 0}
-```
-
-Please note that if you want to create a new user, the pre-login hook response must include all the mandatory user fields.
-
-The program hook must finish within 30 seconds, the HTTP hook will use the global configuration for HTTP clients.
-
-If an error happens while executing the hook then login will be denied.
-
-"Dynamic user creation or modification" and "External Authentication" are mutually exclusive, they are quite similar, the difference is that "External Authentication" returns an already authenticated user while using "Dynamic users modification" you simply create or update a user. The authentication will be checked inside SFTPGo.
-In other words while using "External Authentication" the external program receives the credentials of the user trying to login (for example the cleartext password) and it needs to validate them. While using "Dynamic users modification" the pre-login program receives the user stored inside the dataprovider (it includes the hashed password if any) and it can modify it, after the modification SFTPGo will check the credentials of the user trying to login.
-
-Let's see a very basic example. Our sample program will grant access to the existing user `test_user` only in the time range 10:00-18:00. Other users will not be modified since the program will terminate with no output.
-
-```shell
-#!/bin/bash
-
-CURRENT_TIME=`date +%H:%M`
-if [[ "$SFTPGO_LOGIND_USER" =~ "\"test_user\"" ]]
-then
-  if [[ $CURRENT_TIME > "18:00" || $CURRENT_TIME < "10:00" ]]
-  then
-    echo '{"status":0}'
-  else
-    echo '{"status":1}'
-  fi
-fi
-```
-
-Please note that this is a demo program and it might not work in all cases. For example, the username should be obtained by parsing the JSON serialized user and not by searching the username inside the JSON as shown here.

-Usage:
-  sftpgo [command]
-
-Available Commands:
-  gen          A collection of useful generators
-  help         Help about any command
-  initprovider Initializes and/or updates the configured data provider
-  portable     Serve a single directory

-
-Flags:
-  -h, --help      help for sftpgo
-  -v, --version
-
- Use "sftpgo [command] --help" for more information about a command
-```
-
-The `serve` command supports the following flags:
-
-- `--config-dir` string. Location of the config dir. This directory should contain the configuration file and is used as the base directory for any files that use a relative path (eg. the private keys for the SFTP server, the SQLite or bblot database if you use SQLite or bbolt as data provider). The default value is "." or the value of `SFTPGO_CONFIG_DIR` environment variable.
-- `--config-file` string. Name of the configuration file. It must be the name of a file stored in `config-dir`, not the absolute path to the configuration file. The specified file name must have no extension because we automatically append JSON, YAML, TOML, HCL and Java extensions when we search for the file. The default value is "sftpgo" (and therefore `sftpgo.json`, `sftpgo.yaml` and so on are searched) or the value of `SFTPGO_CONFIG_FILE` environment variable.
-- `--loaddata-from` string. Load users and folders from this file. The file must be specified as absolute path and it must contain a backup obtained using the `dumpdata` REST API or compatible content. The default value is empty or the value of `SFTPGO_LOADDATA_FROM` environment variable.
-- `--loaddata-clean` boolean. Determine if the loaddata-from file should be removed after a successful load. Default `false` or the value of `SFTPGO_LOADDATA_CLEAN` environment variable (1 or `true`, 0 or `false`).
-- `--loaddata-mode`, integer. Restore mode for data to load. 0 means new users are added, existing users are updated. 1 means new users are added, existing users are not modified. Default 1 or the value of `SFTPGO_LOADDATA_MODE` environment variable.
-- `--loaddata-scan`, integer. Quota scan mode after data load. 0 means no quota scan. 1 means quota scan. 2 means scan quota if the user has quota restrictions. Default 0 or the value of `SFTPGO_LOADDATA_QUOTA_SCAN` environment variable.
-- `--log-compress` boolean. Determine if the rotated log files should be compressed using gzip. Default `false` or the value of `SFTPGO_LOG_COMPRESS` environment variable (1 or `true`, 0 or `false`). It is unused if `log-file-path` is empty.
-- `--log-file-path` string. Location for the log file, default "sftpgo.log" or the value of `SFTPGO_LOG_FILE_PATH` environment variable. Leave empty to write logs to the standard error.
-- `--log-max-age` int. Maximum number of days to retain old log files. Default 28 or the value of `SFTPGO_LOG_MAX_AGE` environment variable. It is unused if `log-file-path` is empty.
-- `--log-max-backups` int. Maximum number of old log files to retain. Default 5 or the value of `SFTPGO_LOG_MAX_BACKUPS` environment variable. It is unused if `log-file-path` is empty.
-- `--log-max-size` int. Maximum size in megabytes of the log file before it gets rotated. Default 10 or the value of `SFTPGO_LOG_MAX_SIZE` environment variable. It is unused if `log-file-path` is empty.
-- `--log-verbose` boolean. Enable verbose logs. Default `true` or the value of `SFTPGO_LOG_VERBOSE` environment variable (1 or `true`, 0 or `false`).
-- `--profiler` boolean. Enable the built-in profiler. The profiler will be accessible via HTTP/HTTPS using the base URL "/debug/pprof/". Default `false` or the value of `SFTPGO_PROFILER` environment variable (1 or `true`, 0 or `false`).
-
-Log file can be rotated on demand sending a `SIGUSR1` signal on Unix based systems and using the command `sftpgo service rotatelogs` on Windows.
-
-If you don't configure any private host key, the daemon will use `id_rsa`, `id_ecdsa` and `id_ed25519` in the configuration directory. If these files don't exist, the daemon will attempt to autogenerate them. The server supports any private key format supported by [`crypto/ssh`](https://github.com/golang/crypto/blob/master/ssh/keys.go#L33).
-
-The `gen` command allows to generate completion scripts for your shell and man pages.
-
-## Configuration file
-
-The configuration file contains the following sections:
-
-- **"common"**, configuration parameters shared among all the supported protocols
-  - `idle_timeout`, integer. Time in minutes after which an idle client will be disconnected. 0 means disabled. Default: 15
-  - `upload_mode` integer. 0 means standard: the files are uploaded directly to the requested path. 1 means atomic: files are uploaded to a temporary path and renamed to the requested path when the client ends the upload. Atomic mode avoids problems such as a web server that serves partial files when the files are being uploaded. In atomic mode, if there is an upload error, the temporary file is deleted and so the requested upload path will not contain a partial file. 2 means atomic with resume support: same as atomic but if there is an upload error, the temporary file is renamed to the requested path and not deleted. This way, a client can reconnect and resume the upload.
-  - `actions`, struct. It contains the command to execute and/or the HTTP URL to notify and the trigger conditions. See [Custom Actions](./custom-actions.md) for more details
-    - `execute_on`, list of strings. Valid values are `download`, `upload`, `pre-delete`, `delete`, `rename`, `ssh_cmd`. Leave empty to disable actions.
-    - `hook`, string. Absolute path to the command to execute or HTTP URL to notify.
-  - `setstat_mode`, integer. 0 means "normal mode": requests for changing permissions, owner/group and access/modification times are executed. 1 means "ignore mode": requests for changing permissions, owner/group and access/modification times are silently ignored.
-  - `proxy_protocol`, integer. Support for [HAProxy PROXY protocol](https://www.haproxy.org/download/1.8/doc/proxy-protocol.txt). If you are running SFTPGo behind a proxy server such as HAProxy, AWS ELB or NGNIX, you can enable the proxy protocol. It provides a convenient way to safely transport connection information such as a client's address across multiple layers of NAT or TCP proxies to get the real client IP address instead of the proxy IP. Both protocol versions 1 and 2 are supported. If the proxy protocol is enabled in SFTPGo then you have to enable the protocol in your proxy configuration too. For example, for HAProxy, add `send-proxy` or `send-proxy-v2` to each server configuration line. The following modes are supported:
-    - 0, disabled
-    - 1, enabled. Proxy header will be used and requests without proxy header will be accepted
-    - 2, required. Proxy header will be used and requests without proxy header will be rejected
-  - `proxy_allowed`, List of IP addresses and IP ranges allowed to send the proxy header:
-    - If `proxy_protocol` is set to 1 and we receive a proxy header from an IP that is not in the list then the connection will be accepted and the header will be ignored
-    - If `proxy_protocol` is set to 2 and we receive a proxy header from an IP that is not in the list then the connection will be rejected
-  - `post_connect_hook`, string. Absolute path to the command to execute or HTTP URL to notify. See [Post connect hook](./post-connect-hook.md) for more details. Leave empty to disable
-- **"sftpd"**, the configuration for the SFTP server
-  - `bind_port`, integer. The port used for serving SFTP requests. Default: 2022
-  - `bind_address`, string. Leave blank to listen on all available network interfaces. Default: ""
-  - `idle_timeout`, integer. Deprecated, please use the same key in `common` section.
-  - `max_auth_tries` integer. Maximum number of authentication attempts permitted per connection. If set to a negative number, the number of attempts is unlimited. If set to zero, the number of attempts is limited to 6.
-  - `banner`, string. Identification string used by the server. Leave empty to use the default banner. Default `SFTPGo_<version>`, for example `SSH-2.0-SFTPGo_0.9.5`
-  - `upload_mode` integer. Deprecated, please use the same key in `common` section.
-  - `actions`, struct. Deprecated, please use the same key in `common` section.
-  - `keys`, struct array. Deprecated, please use `host_keys`.
-    - `private_key`, path to the private key file. It can be a path relative to the config dir or an absolute one.
-  - `host_keys`, list of strings. It contains the daemon's private host keys. Each host key can be defined as a path relative to the configuration directory or an absolute one. If empty, the daemon will search or try to generate `id_rsa`, `id_ecdsa` and `id_ed25519` keys inside the configuration directory. If you configure absolute paths to files named `id_rsa`, `id_ecdsa` and/or `id_ed25519` then SFTPGo will try to generate these keys using the default settings.
-  - `kex_algorithms`, list of strings. Available KEX (Key Exchange) algorithms in preference order. Leave empty to use default values. The supported values can be found here: [`crypto/ssh`](https://github.com/golang/crypto/blob/master/ssh/common.go#L46 "Supported kex algos")
-  - `ciphers`, list of strings. Allowed ciphers. Leave empty to use default values. The supported values can be found here: [crypto/ssh](https://github.com/golang/crypto/blob/master/ssh/common.go#L28 "Supported ciphers")
-  - `macs`, list of strings. Available MAC (message authentication code) algorithms in preference order. Leave empty to use default values. The supported values can be found here: [crypto/ssh](https://github.com/golang/crypto/blob/master/ssh/common.go#L84 "Supported MACs")
-  - `trusted_user_ca_keys`, list of public keys paths of certificate authorities that are trusted to sign user certificates for authentication. The paths can be absolute or relative to the configuration directory.
-  - `login_banner_file`, path to the login banner file. The contents of the specified file, if any, are sent to the remote user before authentication is allowed. It can be a path relative to the config dir or an absolute one. Leave empty to disable login banner.
-  - `setstat_mode`, integer. Deprecated, please use the same key in `common` section.
-  - `enabled_ssh_commands`, list of enabled SSH commands. `*` enables all supported commands. More information can be found [here](./ssh-commands.md).
-  - `keyboard_interactive_auth_hook`, string. Absolute path to an external program or an HTTP URL to invoke for keyboard interactive authentication. See [Keyboard Interactive Authentication](./keyboard-interactive.md) for more details.
-  - `password_authentication`, boolean. Set to false to disable password authentication. This setting will disable multi-step authentication method using public key + password too. It is useful for public key only configurations if you need to manage old clients that will not attempt to authenticate with public keys if the password login method is advertised. Default: true.
-  - `proxy_protocol`, integer.  Deprecated, please use the same key in `common` section.
-  - `proxy_allowed`, list of strings. Deprecated, please use the same key in `common` section.
-- **"ftpd"**, the configuration for the FTP server

-  - `banner`, string. Greeting banner displayed when a connection first comes in. Leave empty to use the default banner. Default `SFTPGo <version> ready`, for example `SFTPGo 1.0.0-dev ready`.
-  - `banner_file`, path to the banner file. The contents of the specified file, if any, are displayed when someone connects to the server. It can be a path relative to the config dir or an absolute one. If set, it overrides the banner string provided by the `banner` option. Leave empty to disable.
-  - `active_transfers_port_non_20`, boolean. Do not impose the port 20 for active data transfers. Enabling this option allows to run SFTPGo with less privilege. Default: false.
-  - `force_passive_ip`, ip address. External IP address to expose for passive connections. Leavy empty to autodetect. Defaut: "".
-  - `passive_port_range`, struct containing the key `start` and `end`. Port Range for data connections. Random if not specified. Default range is 50000-50100.
-  - `certificate_file`, string. Certificate for FTPS. This can be an absolute path or a path relative to the config dir.
-  - `certificate_key_file`, string. Private key matching the above certificate. This can be an absolute path or a path relative to the config dir. If both the certificate and the private key are provided the server will accept both plain FTP an explicit FTP over TLS. Certificate and key files can be reloaded on demand sending a `SIGHUP` signal on Unix based systems and a `paramchange` request to the running service on Windows.
-  - `tls_mode`, integer. 0 means accept both cleartext and encrypted sessions. 1 means TLS is required for both control and data connection. Do not enable this blindly, please check that a proper TLS config is in place or no login will be allowed if `tls_mode` is 1.
-- **webdavd**, the configuration for the WebDAV server, more info [here](./webdav.md)
-  - `bind_port`, integer. The port used for serving WebDAV requests. 0 means disabled. Default: 0.
-  - `bind_address`, string. Leave blank to listen on all available network interfaces. Default: "".
-  - `certificate_file`, string. Certificate for WebDAV over HTTPS. This can be an absolute path or a path relative to the config dir.
-  - `certificate_key_file`, string. Private key matching the above certificate. This can be an absolute path or a path relative to the config dir. If both the certificate and the private key are provided the server will expect HTTPS connections. Certificate and key files can be reloaded on demand sending a `SIGHUP` signal on Unix based systems and a `paramchange` request to the running service on Windows.
-  - `cors` struct containing CORS configuration. SFTPGo uses [Go CORS handler](https://github.com/rs/cors), please refer to upstream documentation for fields meaning and their default values.
-    - `enabled`, boolean, set to true to enable CORS.
-    - `allowed_origins`, list of strings.
-    - `allowed_methods`, list of strings.
-    - `allowed_headers`, list of strings.
-    - `exposed_headers`, list of strings.
-    - `allow_credentials` boolean.

-- **"data_provider"**, the configuration for the data provider
-  - `driver`, string. Supported drivers are `sqlite`, `mysql`, `postgresql`, `bolt`, `memory`
-  - `name`, string. Database name. For driver `sqlite` this can be the database name relative to the config dir or the absolute path to the SQLite database. For driver `memory` this is the (optional) path relative to the config dir or the absolute path to the users dump, obtained using the `dumpdata` REST API, to load. This dump will be loaded at startup and can be reloaded on demand sending a `SIGHUP` signal on Unix based systems and a `paramchange` request to the running service on Windows. The `memory` provider will not modify the provided file so quota usage and last login will not be persisted
-  - `host`, string. Database host. Leave empty for drivers `sqlite`, `bolt` and `memory`
-  - `port`, integer. Database port. Leave empty for drivers `sqlite`, `bolt` and `memory`
-  - `username`, string. Database user. Leave empty for drivers `sqlite`, `bolt` and `memory`
-  - `password`, string. Database password. Leave empty for drivers `sqlite`, `bolt` and `memory`

-    - 0, disable quota tracking. REST API to scan users home directories/virtual folders and update quota will do nothing
-    - 1, quota is updated each time a user uploads or deletes a file, even if the user has no quota restrictions
-    - 2, quota is updated each time a user uploads or deletes a file, but only for users with quota restrictions and for virtual folders. With this configuration, the `quota scan` and `folder_quota_scan` REST API can still be used to periodically update space usage for users without quota restrictions and for folders
-  - `pool_size`, integer. Sets the maximum number of open connections for `mysql` and `postgresql` driver. Default 0 (unlimited)
-  - `users_base_dir`, string. Users default base directory. If no home dir is defined while adding a new user, and this value is a valid absolute path, then the user home dir will be automatically defined as the path obtained joining the base dir and the username
-  - `actions`, struct. It contains the command to execute and/or the HTTP URL to notify and the trigger conditions. See [Custom Actions](./custom-actions.md) for more details
-    - `execute_on`, list of strings. Valid values are `add`, `update`, `delete`. `update` action will not be fired for internal updates such as the last login or the user quota fields.
-    - `hook`, string. Absolute path to the command to execute or HTTP URL to notify.
-  - `external_auth_program`, string. Deprecated, please use `external_auth_hook`.
-  - `external_auth_hook`, string. Absolute path to an external program or an HTTP URL to invoke for users authentication. See [External Authentication](./external-auth.md) for more details. Leave empty to disable.
-  - `external_auth_scope`, integer. 0 means all supported authentication scopes (passwords, public keys and keyboard interactive). 1 means passwords only. 2 means public keys only. 4 means key keyboard interactive only. The flags can be combined, for example 6 means public keys and keyboard interactive
-  - `credentials_path`, string. It defines the directory for storing user provided credential files such as Google Cloud Storage credentials. This can be an absolute path or a path relative to the config dir
-  - `prefer_database_credentials`, boolean. When true, users' Google Cloud Storage credentials will be written to the data provider instead of disk, though pre-existing credentials on disk will be used as a fallback. When false, they will be written to the directory specified by `credentials_path`.
-  - `pre_login_program`, string. Deprecated, please use `pre_login_hook`.
-  - `pre_login_hook`, string. Absolute path to an external program or an HTTP URL to invoke to modify user details just before the login. See [Dynamic user modification](./dynamic-user-mod.md) for more details. Leave empty to disable.
-  - `post_login_hook`, string. Absolute path to an external program or an HTTP URL to invoke to notify a successful or failed login. See [Post-login hook](./post-login-hook.md) for more details. Leave empty to disable.
-  - `post_login_scope`, defines the scope for the post-login hook. 0 means notify both failed and successful logins. 1 means notify failed logins. 2 means notify successful logins.
-  - `check_password_hook`, string.  Absolute path to an external program or an HTTP URL to invoke to check the user provided password. See [Check password hook](./check-password-hook.md) for more details. Leave empty to disable.
-  - `check_password_scope`, defines the scope for the check password hook. 0 means all protocols, 1 means SSH, 2 means FTP, 4 means WebDAV. You can combine the scopes, for example 6 means FTP and WebDAV.
-  - `password_hashing`, struct. It contains the configuration parameters to be used to generate the password hash. SFTPGo can verify passwords in several formats and uses the `argon2id` algorithm to hash passwords in plain-text before storing them inside the data provider. These options allow you to customize how the hash is generated.
-    - `argon2_options` struct containing the options for argon2id hashing algorithm. The `memory` and `iterations` parameters control the computational cost of hashing the password. The higher these figures are, the greater the cost of generating the hash and the longer the runtime. It also follows that the greater the cost will be for any attacker trying to guess the password. If the code is running on a machine with multiple cores, then you can decrease the runtime without reducing the cost by increasing the `parallelism` parameter. This controls the number of threads that the work is spread across.
-      - `memory`, unsigned integer. The amount of memory used by the algorithm (in kibibytes). Default: 65536.
-      - `iterations`, unsigned integer. The number of iterations over the memory. Default: 1.
-      - `parallelism`. unsigned 8 bit integer. The number of threads (or lanes) used by the algorithm. Default: 2.
-  - `update_mode`, integer. Defines how the database will be initialized/updated. 0 means automatically. 1 means manually using the initprovider sub-command.
-- **"httpd"**, the configuration for the HTTP server used to serve REST API and to expose the built-in web interface
-  - `bind_port`, integer. The port used for serving HTTP requests. Set to 0 to disable HTTP server. Default: 8080
-  - `bind_address`, string. Leave blank to listen on all available network interfaces. Default: "127.0.0.1"
-  - `templates_path`, string. Path to the HTML web templates. This can be an absolute path or a path relative to the config dir
-  - `static_files_path`, string. Path to the static files for the web interface. This can be an absolute path or a path relative to the config dir. If both `templates_path` and `static_files_path` are empty the built-in web interface will be disabled
-  - `backups_path`, string. Path to the backup directory. This can be an absolute path or a path relative to the config dir. We don't allow backups in arbitrary paths for security reasons
-  - `auth_user_file`, string. Path to a file used to store usernames and passwords for basic authentication. This can be an absolute path or a path relative to the config dir. We support HTTP basic authentication, and the file format must conform to the one generated using the Apache `htpasswd` tool. The supported password formats are bcrypt (`$2y$` prefix) and md5 crypt (`$apr1$` prefix). If empty, HTTP authentication is disabled.
-  - `certificate_file`, string. Certificate for HTTPS. This can be an absolute path or a path relative to the config dir.
-  - `certificate_key_file`, string. Private key matching the above certificate. This can be an absolute path or a path relative to the config dir. If both the certificate and the private key are provided, the server will expect HTTPS connections. Certificate and key files can be reloaded on demand sending a `SIGHUP` signal on Unix based systems and a `paramchange` request to the running service on Windows.
-- **"http"**, the configuration for HTTP clients. HTTP clients are used for executing hooks such as the ones used for custom actions, external authentication and pre-login user modifications
-  - `timeout`, integer. Timeout specifies a time limit, in seconds, for requests.
-  - `ca_certificates`, list of strings. List of paths to extra CA certificates to trust. The paths can be absolute or relative to the config dir. Adding trusted CA certificates is a convenient way to use self-signed certificates without defeating the purpose of using TLS.
-  - `skip_tls_verify`, boolean. if enabled the HTTP client accepts any TLS certificate presented by the server and any host name in that certificate. In this mode, TLS is susceptible to man-in-the-middle attacks. This should be used only for testing.
-
-A full example showing the default config (in JSON format) can be found [here](../sftpgo.json).
-
-If you want to use a private host key that uses an algorithm/setting different from the auto generated RSA/ECDSA keys, or more than two private keys, you can generate your own keys and replace the empty `keys` array with something like this:
-
-```json
-"host_keys": [
-  "id_rsa",
-  "id_ecdsa",
-  "id_ed25519"
-]
-```
-
-where `id_rsa`, `id_ecdsa` and `id_ed25519`, in this example, are files containing your generated keys. You can use absolute paths or paths relative to the configuration directory specified via the `--config-dir` serve flag. By default the configuration directory is the working directory.
-
-If you want the default host keys generation in a directory different from the config dir, please specify absolute paths to files named `id_rsa`, `id_ecdsa` or `id_ed25519` like this:
-
-```json
-"host_keys": [
-  "/etc/sftpgo/keys/id_rsa",
-  "/etc/sftpgo/keys/id_ecdsa",
-  "/etc/sftpgo/keys/id_ed25519"
-]
-```
-
-then SFTPGo will try to create `id_rsa`, `id_ecdsa` and `id_ed25519`, if they are missing, inside the directory `/etc/sftpgo/keys`.
-
-The configuration can be read from JSON, TOML, YAML, HCL, envfile and Java properties config files. If your `config-file` flag is set to `sftpgo` (default value), you need to create a configuration file called `sftpgo.json` or `sftpgo.yaml` and so on inside `config-dir`.
-
-## Environment variables
-
-You can also override all the available configuration options using environment variables. SFTPGo will check for environment variables with a name matching the key uppercased and prefixed with the `SFTPGO_`. You need to use `__` to traverse a struct.
-
-Let's see some examples:
-
-- To set sftpd `bind_port`, you need to define the env var `SFTPGO_SFTPD__BIND_PORT`
-- To set the `execute_on` actions, you need to define the env var `SFTPGO_COMMON__ACTIONS__EXECUTE_ON`. For example `SFTPGO_COMMON__ACTIONS__EXECUTE_ON=upload,download`

-# Google Cloud Storage backend
-
-To connect SFTPGo to Google Cloud Storage you can use use the Application Default Credentials (ADC) strategy to try to find your application's credentials automatically or you can explicitly provide a JSON credentials file that you can obtain from the Google Cloud Console. Take a look [here](https://cloud.google.com/docs/authentication/production#providing_credentials_to_your_application) for details.
-
-Specifying a different `key_prefix`, you can assign different "folders" of the same bucket to different users. This is similar to a chroot directory for local filesystem. Each SFTP/SCP user can only access the assigned folder and its contents. The folder identified by `key_prefix` does not need to be pre-created.
-
-You can optionally specify a [storage class](https://cloud.google.com/storage/docs/storage-classes) too. Leave it blank to use the default storage class.
-
-The configured bucket must exist.
-
-This backend is very similar to the [S3](./s3.md) backend, and it has the same limitations.

-# SFTPGo with PostgreSQL data provider and S3 backend
-
-This tutorial shows the installation of SFTPGo on Ubuntu 20.04 (Focal Fossa) with PostgreSQL data provider and S3 backend. SFTPGo will run as an unprivileged (non-root) user. We assume that you want to serve a single S3 bucket and you want to assign different "virtual folders" of this bucket to different SFTPGo virtual users.
-
-## Preliminary Note
-
-Before proceeding further you need to have a basic minimal installation of Ubuntu 20.04.
-
-## Install PostgreSQL
-
-Before installing any packages on the Ubuntu system, update and upgrade all packages using the `apt` commands below.
-
-```shell
-sudo apt update
-sudo apt upgrade
-```
-
-Install PostgreSQL with this `apt` command.
-
-```shell
-sudo apt -y install postgresql
-```
-
-Once installation is completed, start the PostgreSQL service and add it to the system boot.
-
-```shell
-sudo systemctl start postgresql
-sudo systemctl enable postgresql
-```
-
-Next, check the PostgreSQL service using the following command.
-
-```shell
-systemctl status postgresql
-```
-
-## Configure PostgreSQL
-
-PostgreSQL uses roles for user authentication and authorization, it just like Unix-Style permissions. By default, PostgreSQL creates a new user called `postgres` for basic authentication.
-
-In this step, we will create a new PostgreSQL user for SFTPGo.
-
-Login to the PostgreSQL shell using the command below.
-
-```shell
-sudo -i -u postgres psql
-```
-
-Next, create a new role `sftpgo` with the password `sftpgo_pg_pwd` using the following query.
-
-```sql
-create user "sftpgo" with encrypted password 'sftpgo_pg_pwd';
-```
-
-Next, create a new database `sftpgo.db` for the SFTPGo service using the following queries.
-
-```sql
-create database "sftpgo.db";
-grant all privileges on database "sftpgo.db" to "sftpgo";
-```
-
-Exit from the PostgreSQL shell typing `\q`.
-
-## Install SFTPGo
-
-To install SFTPGo you can use the PPA [here](https://launchpad.net/~sftpgo/+archive/ubuntu/sftpgo).
-
-Start by adding the PPA.
-
-```shell
-sudo add-apt-repository ppa:sftpgo/sftpgo
-sudo apt-get update
-```
-
-Next install SFTPGo.
-
-```shell
-sudo apt install sftpgo
-```
-
-After installation SFTPGo should already be running with default configuration and configured to start automatically at boot, check its status using the following command.
-
-```shell
-systemctl status sftpgo
-```
-
-## Configure AWS credentials
-
-We assume that you want to serve a single S3 bucket and you want to assign different "virtual folders" of this bucket to different SFTPGo virtual users. In this case is very convenient to configure a credential file so SFTPGo will automatically use it and you don't need to specify the same AWS credentials for each user.
-
-You can manually create the `/var/lib/sftpgo/.aws/credentials` file and write your AWS credentials like this.
-
-```shell
-[default]
-aws_access_key_id=AKIAIOSFODNN7EXAMPLE
-aws_secret_access_key=wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY
-```
-
-Alternately you can install `AWS CLI` and manage the credential using this tool.
-
-```shell
-sudo apt install awscli
-```
-
-and now set your credentials, region, and output format with the following command.
-
-```shell
-aws configure
-```
-
-Confirm that you can list your bucket contents with the following command.
-
-```shell
-aws s3 ls s3://mybucket
-```
-
-The AWS CLI will create the credential file in `~/.aws/credentials`. The SFTPGo service runs using the `sftpgo` system user whose home directory is `/var/lib/sftpgo` so you need to copy the credentials file to the sftpgo home directory and assign it the proper permissions.
-
-```shell
-sudo mkdir /var/lib/sftpgo/.aws
-sudo cp ~/.aws/credentials /var/lib/sftpgo/.aws/
-sudo chown -R sftpgo:sftpgo /var/lib/sftpgo/.aws
-```
-
-## Configure SFTPGo
-
-Now open the SFTPGo configuration.
-
-```shell
-sudo vi /etc/sftpgo/sftpgo.json
-```
-
-Search for the `data_provider` section and change it as follow.
-
-```json
-  "data_provider": {
-    "driver": "postgresql",
-    "name": "sftpgo.db",
-    "host": "127.0.0.1",
-    "port": 5432,
-    "username": "sftpgo",
-    "password": "sftpgo_pg_pwd",
-    ...
-}
-```
-
-This way we set the PostgreSQL connection parameters.
-
-If you want to connect to PostgreSQL over a Unix Domain socket you have to set the value `/var/run/postgresql` for the `host` configuration key instead of `127.0.0.1`.
-
-You can further customize your configuration adding custom actions and other hooks. A full explanation of all configuration parameters can be found [here](../full-configuration.md).
-
-Next, initialize the data provider with the following command.
-
-```shell
-$ sudo su - sftpgo -s /bin/bash -c 'sftpgo initprovider -c /etc/sftpgo'
-2020-10-09T21:07:50.000 INF Initializing provider: "postgresql" config file: "/etc/sftpgo/sftpgo.json"
-2020-10-09T21:07:50.000 INF updating database version: 1 -> 2
-2020-10-09T21:07:50.000 INF updating database version: 2 -> 3
-2020-10-09T21:07:50.000 INF updating database version: 3 -> 4
-2020-10-09T21:07:50.000 INF Data provider successfully initialized/updated
-```
-
-The default sftpgo systemd service will start after the network target, in this setup it is more appropriate to start it after the PostgreSQL service, so edit the service using the following command.
-
-```shell
-sudo systemctl edit sftpgo.service
-```
-
-And override the unit definition with the following snippet.
-
-```shell
-[Unit]
-After=postgresql.service
-```
-
-Confirm that `sftpgo.service` will start after `postgresql.service` with the next command.
-
-```shell
-$ systemctl show sftpgo.service | grep After=
-After=postgresql.service systemd-journald.socket system.slice -.mount systemd-tmpfiles-setup.service network.target sysinit.target basic.target
-```
-
-Next restart the sftpgo service to use the new configuration and check that it is running.
-
-```shell
-sudo systemctl restart sftpgo
-systemctl status sftpgo
-```
-
-## Add virtual users
-
-The easiest way to add virtual users is to use the built-in Web interface.
-
-You can expose the Web Admin interface over the network replacing `"bind_address": "127.0.0.1"` in the `httpd` configuration section with `"bind_address": ""` and apply the change restarting the SFTPGo service with the following command.
-
-```shell
-sudo systemctl restart sftpgo
-```
-
-So now open the Web Admin URL.
-
-[http://127.0.0.1:8080/web](http://127.0.0.1:8080/web)
-
-Click `Add` and fill the user details, the minimum required parameters are:
-
-- `Username`
-- `Password` or `Public keys`
-- `Permissions`
-- `Home Dir` can be empty since we defined a default base dir
-- Select `AWS S3 (Compatible)` as storage and then set `Bucket`, `Region` and optionally a `Key Prefix` if you want to restrict the user to a specific virtual folder in the bucket. The specified virtual folder does not need to be pre-created. You can leave `Access Key` and `Access Secret` empty since we defined global credentials for the `sftpgo` user and we use this system user to run the SFTPGo service.
-
-You are done! Now you can connect to you SFTPGo instance using any compatible `sftp` client on port `2022`.
-
-You can mix S3 users with local users but please be aware that we are running the service as the unprivileged `sftpgo` system user so if you set storage as `local` for an SFTPGo virtual user then the home directory for this user must be owned by the `sftpgo` system user. If you don't specify an home directory the default will be `/srv/sftpgo/data/<username>` which should be appropriate.

-# Expose Web Admin and REST API over HTTPS and password protected
-
-This tutorial shows how to expose the SFTPGo web interface and REST API over HTTPS and password protect them.
-
-## Preliminary Note
-
-Before proceeding further you need to have a SFTPGo instance already configured and running.
-
-We assume:
-
-- you are running SFTPGo as service using the dedicated `sftpgo` system user
-- the SFTPGo configuration directory is `/etc/sftpgo`
-- you are running SFTPGo on Ubuntu 20.04, however this instructions can be easily adapted for other Linux variants.
-
-## Authentication Setup
-
-First install the `htpasswd` tool. We use this tool to create the users for the Web Admin/REST API.
-
-```shell
-sudo apt install apache2-utils
-```
-
-Create a user for web based authentication.
-
-```shell
-sudo htpasswd -B -c /etc/sftpgo/httpauth sftpgoweb
-```
-
-If you want to create additional users omit the `-c` option.
-
-```shell
-sudo htpasswd -B /etc/sftpgo/httpauth anotheruser
-```
-
-Next open the SFTPGo configuration.
-
-```shell
-sudo vi /etc/sftpgo/sftpgo.json
-```
-
-Search for the `httpd` section and change it as follow.
-
-```json
-  "httpd": {
-    "bind_port": 8080,
-    "bind_address": "",
-    "templates_path": "templates",
-    "static_files_path": "static",
-    "backups_path": "backups",
-    "auth_user_file": "/etc/sftpgo/httpauth",
-    "certificate_file": "",
-    "certificate_key_file": ""
-  }
-```
-
-Setting an empty `bind_address` means that the service will listen on all available network interfaces and so it will be exposed over the network.
-
-Now restart the SFTPGo service to apply the changes.
-
-```shell
-sudo systemctl restart sftpgo
-```
-
-You are done! Now login to the Web Admin interface using the username and password created above.
-
-## Creation of a Self-Signed Certificate
-
-For demostration purpose we use a self-signed certificate here. These certificates are easy to make and do not cost money. However, they do not provide all of the security properties that certificates signed by a Public Certificate Authority (CA) aim to provide, you are encouraged to use a certificate signed by a Public CA.
-
-When creating a new SSL certificate, one needs to specify the duration validity of the same by changing the value 365 (as appearing in the message below) to the preferred number of days. It is important to mention here that the certificate so created stands to auto-expire upon completion of one year.
-
-```shell
-sudo mkdir /etc/sftpgo/ssl
-sudo openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout /etc/sftpgo/ssl/sftpgo.key -out /etc/sftpgo/ssl/sftpgo.crt
-```
-
-The above command is rather versatile, and lets you create both the self-signed SSL certificate and the server key to safeguard it, in addition to placing both of these into the `etc/sftpgo/ssl` directory. Answer to the questions to create the certificate and the key for HTTPS.
-
-Assign the proper permissions to the generated certificates.
-
-```shell
-sudo chown -R sftpgo:sftpgo /etc/sftpgo/ssl
-```
-
-## HTTPS Setup
-
-Open the SFTPGo configuration.
-
-```shell
-sudo vi /etc/sftpgo/sftpgo.json
-```
-
-Search for the `httpd` section and change it as follow.
-
-```json
-  "httpd": {
-    "bind_port": 8080,
-    "bind_address": "",
-    "templates_path": "templates",
-    "static_files_path": "static",
-    "backups_path": "backups",
-    "auth_user_file": "/etc/sftpgo/httpauth",
-    "certificate_file": "/etc/sftpgo/ssl/sftpgo.crt",
-    "certificate_key_file": "/etc/sftpgo/ssl/sftpgo.key"
-  }
-```
-
-Now restart the SFTPGo service to apply the changes.
-
-```shell
-sudo systemctl restart sftpgo
-```
-
-You are done! Now SFTPGo web admin and REST API are exposed over HTTPS and password protected.
-
-You can easily replace the self-signed certificate used here with a properly signed certificate.
-
-The certificate could frequently change if you use something like [let's encrypt](https://letsencrypt.org/). SFTPGo allows hot-certificate reloading using the following command.
-
-```shell
-sudo systemctl reload sftpgo
-```

-There are no restrictions on the number of questions asked on a particular authentication stage; there are also no restrictions on the number of stages involving different sets of questions.
-
-To enable keyboard interactive authentication, you must set the absolute path of your authentication program or an HTTP URL using the  `keyboard_interactive_auth_hook` key in your configuration file.
-
-The external program can read the following environment variables to get info about the user trying to authenticate:
-
-- `SFTPGO_AUTHD_USERNAME`
-- `SFTPGO_AUTHD_IP`
-- `SFTPGO_AUTHD_PASSWORD`, this is the hashed password as stored inside the data provider
-
-Previous global environment variables aren't cleared when the script is called. The content of these variables is _not_ quoted. They may contain special characters.
-
-The program must write the questions on its standard output, in a single line, using the following struct JSON serialized:
-
-- `instruction`, string. A short description to show to the user that is trying to authenticate. Can be empty or omitted
-- `questions`, list of questions to be asked to the user
-- `echos` list of boolean flags corresponding to the questions (so the lengths of both lists must be the same) and indicating whether user's reply for a particular question should be echoed on the screen while they are typing: true if it should be echoed, or false if it should be hidden.
-- `check_password` optional integer. Ask exactly one question and set this field to 1 if the expected answer is the user password and you want that SFTPGo checks it for you. If the password is correct, the returned response to the program is `OK`. If the password is wrong, the program will be terminated and an authentication error will be returned to the user that is trying to authenticate.
-- `auth_result`, integer. Set this field to 1 to indicate successful authentication. 0 is ignored. Any other value means authentication error. If this field is found and it is different from 0 then SFTPGo will not read any other questions from the external program, and it will finalize the authentication.
-
-SFTPGo writes the user answers to the program standard input, one per line, in the same order as the questions.
-Please be sure that your program receives the answers for all the issued questions before asking for the next ones.
-
-Keyboard interactive authentication can be chained to the external authentication.
-The authentication must finish within 60 seconds.
-
-Let's see a very basic example. Our sample keyboard interactive authentication program will ask for 2 sets of questions and accept the user if the answer to the last question is `answer3`.
-
-```shell
-#!/bin/sh
-
-echo '{"questions":["Question1: ","Question2: "],"instruction":"This is a sample for keyboard interactive authentication","echos":[true,false]}'
-
-read ANSWER1
-read ANSWER2
-
-echo '{"questions":["Question3: "],"instruction":"","echos":[true]}'
-
-read ANSWER3
-
-if test "$ANSWER3" = "answer3"; then
-  echo '{"auth_result":1}'
-else
-  echo '{"auth_result":-1}'
-fi
-```
-
-and here is an example where SFTPGo checks the user password for you:
-
-```shell
-#!/bin/sh
-
-echo '{"questions":["Password: "],"instruction":"This is a sample for keyboard interactive authentication","echos":[false],"check_password":1}'
-
-read ANSWER1
-
-if test "$ANSWER1" != "OK"; then
-  exit 1
-fi
-
-echo '{"questions":["One time token: "],"instruction":"","echos":[false]}'
-
-read ANSWER2
-
-if test "$ANSWER2" = "token"; then
-  echo '{"auth_result":1}'
-else
-  echo '{"auth_result":-1}'
-fi
-```
-
-If the hook is an HTTP URL then it will be invoked as HTTP POST multiple times for each login request.
-The request body will contain a JSON struct with the following fields:
-
-- `request_id`, string. Unique request identifier
-- `username`, string
-- `ip`, string
-- `password`, string. This is the hashed password as stored inside the data provider
-- `answers`, list of string. It will be null for the first request
-- `questions`, list of string. It will contain the previously asked questions. It will be null for the first request
-
-The HTTP response code must be 200 and the body must contain the same JSON struct described for the program.
-
-Let's see a basic sample, the configured hook is `http://127.0.0.1:8000/keyIntHookPwd`, as soon as the user tries to login, SFTPGo makes this HTTP POST request:
-
-```shell
-POST /keyIntHookPwd HTTP/1.1
-Host: 127.0.0.1:8000
-User-Agent: Go-http-client/1.1
-Content-Length: 189
-Content-Type: application/json
-Accept-Encoding: gzip
-
-{"request_id":"bq1r5r7cdrpd2qtn25ng","username":"a","ip":"127.0.0.1","password":"$pbkdf2-sha512$150000$ClOPkLNujMTL$XktKy0xuJsOfMYBz+f2bIyPTdbvDTSnJ1q+7+zp/HPq5Qojwp6kcpSIiVHiwvbi8P6HFXI/D3UJv9BLcnQFqPA=="}
-```
-
-as you can see in this first requests `answers` and `questions` are null.
-
-Here is the response that instructs SFTPGo to ask for the user password and to check it:
-
-```shell
-HTTP/1.1 200 OK

-Content-Length: 143
-
-{"questions": ["Password: "], "check_password": 1, "instruction": "This is a sample for keyboard interactive authentication", "echos": [false]}
-```
-
-The user enters the correct password and so SFTPGo makes a new HTTP POST, please note that the `request_id` is the same of the previous request, this time the asked `questions` and the user's `answers` are not null:
-
-```shell
-POST /keyIntHookPwd HTTP/1.1

-```
-
-Here is the HTTP response that instructs SFTPGo to ask for a new question:
-
-```shell
-HTTP/1.1 200 OK

-X-Frame-Options: SAMEORIGIN
-Content-Length: 66
-
-{"questions": ["Question2: "], "instruction": "", "echos": [true]}
-```
-
-As soon as the user answer to this question, SFTPGo will make a new HTTP POST request with the user's answers:
-
-```shell
-POST /keyIntHookPwd HTTP/1.1
-Host: 127.0.0.1:8000
-User-Agent: Go-http-client/1.1

-```
-
-Here is the final HTTP response that allows the user login:
-
-```shell
-HTTP/1.1 200 OK
-Date: Tue, 31 Mar 2020 21:15:29 GMT
-Server: WSGIServer/0.2 CPython/3.8.2

-# Performance
-
-SFTPGo can easily saturate a Gigabit connection on low end hardware with no special configuration, this is generally enough for most use cases.
-
-For Multi-Gig connections, some performance improvements and comparisons with OpenSSH have been discussed [here](https://github.com/drakkan/sftpgo/issues/69), most of them have been included in the master branch. To summarize:
-
-- In current state with all performance improvements applied, SFTP performance is very close to OpenSSH however CPU usage is higher. SCP performance match OpenSSH.
-- The main bottlenecks are the encryption and the messages authentication, so if you can use a fast cipher with implicit messages authentication, such as `aes128-gcm@openssh.com`, you will get a big performance boost.
-- SCP protocol is much simpler than SFTP and so, the multi-platform, SFTPGo's SCP implementation performs better than SFTP.
-- Load balancing with HAProxy can greatly improve the performance if CPU not become the bottleneck.

-# Profiling SFTPGo
-
-The built-in profiler lets you collect CPU profiles, traces, allocations and heap profiles that allow to identify and correct specific bottlenecks.
-You can enable the built-in profiler using the `--profiler` command flag.
-
-Profiling data are exposed via HTTP/HTTPS in the format expected by the [pprof](https://github.com/google/pprof/blob/master/doc/README.md) visualization tool. You can find the index page at the URL `/debug/pprof/`.
-
-The following profiles are available, you can obtain them via HTTP GET requests:
-
-- `allocs`, a sampling of all past memory allocations
-- `block`, stack traces that led to blocking on synchronization primitives
-- `goroutine`, stack traces of all current goroutines
-- `heap`, a sampling of memory allocations of live objects. You can specify the `gc` GET parameter to run GC before taking the heap sample
-- `mutex`, stack traces of holders of contended mutexes
-- `profile`, CPU profile. You can specify the duration in the `seconds` GET parameter. After you get the profile file, use the `go tool pprof` command to investigate the profile
-- `threadcreate`, stack traces that led to the creation of new OS threads
-- `trace`, a trace of execution of the current program. You can specify the duration in the `seconds` GET parameter. After you get the trace file, use the `go tool trace` command to investigate the trace
-
-For example you can:
-
-- download a 30 seconds CPU profile from the URL `/debug/pprof/profile?seconds=30`
-- download a sampling of memory allocations of live objects from the URL `/debug/pprof/heap?gc=1`
-- download a sampling of all past memory allocations from the URL `/debug/pprof/allocs`

-# REST API
-
-SFTPGo exposes REST API to manage, backup, and restore users and folders, and to get real time reports of the active connections with the ability to forcibly close a connection.
-
-If quota tracking is enabled in the configuration file, then the used size and number of files are updated each time a file is added/removed. If files are added/removed not using SFTP/SCP, or if you change `track_quota` from `2` to `1`, you can rescan the users home dir and update the used quota using the REST API.
-
-REST API can be protected using HTTP basic authentication and exposed via HTTPS. If you need more advanced security features, you can setup a reverse proxy using an HTTP Server such as Apache or NGNIX.
-
-For example, you can keep SFTPGo listening on localhost and expose it externally configuring a reverse proxy using Apache HTTP Server this way:
-
-```shell
-ProxyPass /api/v1 http://127.0.0.1:8080/api/v1
-ProxyPassReverse /api/v1 http://127.0.0.1:8080/api/v1
-```
-
-and you can add authentication with something like this:
-
-```shell
-<Location /api/v1>
-  AuthType Digest
-  AuthName "Private"
-  AuthDigestDomain "/api/v1"
-  AuthDigestProvider file
-  AuthUserFile "/etc/httpd/conf/auth_digest"
-  Require valid-user
-</Location>
-```
-
-and, of course, you can configure the web server to use HTTPS.
-
-The OpenAPI 3 schema for the exposed API can be found inside the source tree: [openapi.yaml](../httpd/schema/openapi.yaml "OpenAPI 3 specs").
-
-A sample CLI client for the REST API can be found inside the source tree [rest-api-cli](../examples/rest-api-cli) directory.
-
-You can also generate your own REST client in your preferred programming language, or even bash scripts, using an OpenAPI generator such as [swagger-codegen](https://github.com/swagger-api/swagger-codegen) or [OpenAPI Generator](https://openapi-generator.tech/)

-# S3 Compatible Object Storage backends
-
-To connect SFTPGo to AWS, you need to specify credentials, a `bucket` and a `region`. Here is the list of available [AWS regions](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/using-regions-availability-zones.html#concepts-available-regions). For example, if your bucket is at `Frankfurt`, you have to set the region to `eu-central-1`. You can specify an AWS [storage class](https://docs.aws.amazon.com/AmazonS3/latest/dev/storage-class-intro.html) too. Leave it blank to use the default AWS storage class. An endpoint is required if you are connecting to a Compatible AWS Storage such as [MinIO](https://min.io/).
-
-AWS SDK has different options for credentials. [More Detail](https://docs.aws.amazon.com/sdk-for-go/v1/developer-guide/configuring-sdk.html). We support:
-
-1. Providing [Access Keys](https://docs.aws.amazon.com/general/latest/gr/aws-sec-cred-types.html#access-keys-and-secret-access-keys).
-2. Use IAM roles for Amazon EC2
-3. Use IAM roles for tasks if your application uses an ECS task definition
-
-So, you need to provide access keys to activate option 1, or leave them blank to use the other ways to specify credentials.
-
-Specifying a different `key_prefix`, you can assign different "folders" of the same bucket to different users. This is similar to a chroot directory for local filesystem. Each SFTP/SCP user can only access the assigned folder and its contents. The folder identified by `key_prefix` does not need to be pre-created.
-
-SFTPGo uses multipart uploads and parallel downloads for storing and retrieving files from S3.
-
-For multipart uploads you can customize the parts size and the upload concurrency. Please note that if the upload bandwidth between the client and SFTPGo is greater than the upload bandwidth between SFTPGo and S3 then the client should wait for the last parts to be uploaded to S3 after finishing uploading the file to SFTPGo, and it may time out. Keep this in mind if you customize these parameters.
-
-The configured bucket must exist.
-
-Some SFTP commands don't work over S3:
-
-- `symlink` and `chtimes` will fail
-- `chown` and `chmod` are silently ignored
-- `truncate` is not supported
-- opening a file for both reading and writing at the same time is not supported
-- upload resume is not supported
-- upload mode `atomic` is ignored since S3 uploads are already atomic
-
-Other notes:
-
-- `rename` is a two step operation: server-side copy and then deletion. So, it is not atomic as for local filesystem.
-- We don't support renaming non empty directories since we should rename all the contents too and this could take a long time: think about directories with thousands of files: for each file we should do an AWS API call.
-- For server side encryption, you have to configure the mapped bucket to automatically encrypt objects.
-- A local home directory is still required to store temporary files.
-- Clients that require advanced filesystem-like features such as `sshfs` are not supported.

-## Windows
-
-On Windows, you can register SFTPGo as Windows Service. Take a look at the CLI usage to learn how to do this:
-
-```powershell
-PS> sftpgo.exe service --help
-Manage SFTPGo Windows Service
-
-Usage:
-  sftpgo service [command]
-
-Available Commands:
-  install     Install SFTPGo as Windows Service
-  reload      Reload the SFTPGo Windows Service sending a "paramchange" request
-  rotatelogs  Signal to the running service to rotate the logs
-  start       Start SFTPGo Windows Service
-  status      Retrieve the status for the SFTPGo Windows Service
-  stop        Stop SFTPGo Windows Service
-  uninstall   Uninstall SFTPGo Windows Service
-
-Flags:
-  -h, --help   help for service
-
-Use "sftpgo service [command] --help" for more information about a command.
-```
-
-The `install` subcommand accepts the same flags that are valid for `serve`.
-
-After installing as a Windows Service, please remember to allow network access to the SFTPGo executable using something like this:
-
-```powershell
-PS> netsh advfirewall firewall add rule name="SFTPGo Service" dir=in action=allow program="C:\Program Files\SFTPGo\sftpgo.exe"
-```
-
-Or through the Windows Firewall GUI.
-
-The Windows installer will register the service and allow network access for it automatically.

-# SSH commands
-
-Some SSH commands are implemented directly inside SFTPGo, while for others we use system commands that need to be installed and in your system's `PATH`.
-
-For system commands we have no direct control on file creation/deletion and so there are some limitations:
-
-- we cannot allow them if the target directory contains virtual folders or file extensions filters
-- system commands work only on local filyestem
-- we cannot avoid to leak real filesystem paths
-- quota check is suboptimal
-- maximum size restriction on single file is not respected
-
- If quota is enabled and SFTPGo receives a system command, the used size and number of files are checked at the command start and not while new files are created/deleted. While the command is running the number of files is not checked, the remaining size is calculated as the difference between the max allowed quota and the used one, and it is checked against the bytes transferred via SSH. The command is aborted if it uploads more bytes than the remaining allowed size calculated at the command start. Anyway, we only see the bytes that the remote command sends to the local one via SSH. These bytes contain both protocol commands and files, and so the size of the files is different from the size transferred via SSH: for example, a command can send compressed files, or a protocol command (few bytes) could delete a big file. To mitigate these issues, quotas are recalculated at the command end with a full scan of the directory specified for the system command. This could be heavy for big directories. If you need system commands and quotas you could consider disabling quota restrictions and periodically update quota usage yourself using the REST API.
-
- For these reasons we should limit system commands usage as much as possible, we currently support the following system commands:
-
-- `git-receive-pack`, `git-upload-pack`, `git-upload-archive`. These commands enable support for Git repositories over SSH. They need to be installed and in your system's `PATH`.
-- `rsync`. The `rsync` command needs to be installed and in your system's `PATH`.
-
-At least the following permissions are required to be able to run system commands:
-
-- `list`
-- `download`
-- `upload`
-- `create_dirs`
-- `overwrite`
-- `delete`
-
-For `rsync`  we cannot avoid that it creates symlinks so if the `create_symlinks` permission is granted we add the option `--safe-links`, if it is not already set, to the received `rsync` command. This should prevent to create symlinks that point outside the home directory.
-If the user cannot create symlinks we add the option `--munge-links`, if it is not already set, to the received `rsync` command. This should make symlinks unusable (but manually recoverable).
-
-SFTPGo supports the following built-in SSH commands:
-
-- `scp`, SFTPGo implements the SCP protocol so we can support it for cloud filesystems too and we can avoid the other system commands limitations. SCP between two remote hosts is supported using the `-3` scp option.
-- `md5sum`, `sha1sum`, `sha256sum`, `sha384sum`, `sha512sum`. Useful to check message digests for uploaded files.
-- `cd`, `pwd`. Some SFTP clients do not support the SFTP SSH_FXP_REALPATH packet type, so they use `cd` and `pwd` SSH commands to get the initial directory. Currently `cd` does nothing and `pwd` always returns the `/` path.
-- `sftpgo-copy`. This is a built-in copy implementation. It allows server side copy for files and directories. The first argument is the source file/directory and the second one is the destination file/directory, for example `sftpgo-copy <src> <dst>`. The command will fail if the destination exists. Copy for directories spanning virtual folders is not supported. Only local filesystem is supported: recursive copy for Cloud Storage filesystems requires a new request for every file in any case, so a real server side copy is not possible.
-- `sftpgo-remove`. This is a built-in remove implementation. It allows to remove single files and to recursively remove directories. The first argument is the file/directory to remove, for example `sftpgo-remove <dst>`. Only local filesystem is supported: recursive remove for Cloud Storage filesystems requires a new request for every file in any case, so a server side remove is not possible.

-The following SSH commands are enabled by default:
-
-- `md5sum`
-- `sha1sum`
-- `cd`
-- `pwd`
-- `scp`

-# Virtual Folders
-
-A virtual folder is a mapping between an SFTP/SCP virtual path and a filesystem path outside the user home directory.
-The specified paths must be absolute and the virtual path cannot be "/", it must be a sub directory.
-The parent directory to the specified virtual path must exist. SFTPGo will try to automatically create any missing parent directory for the configured virtual folders at user login.
-
-For each virtual folder, the following properties can be configured:
-
-- `mapped_path`, the full absolute path to the filesystem path to expose as virtual folder
-- `virtual_path`, the SFTP/SCP absolute path to use to expose the mapped path
-- `quota_size`, maximum size allowed as bytes. 0 means unlimited, -1 included in user quota
-- `quota_files`, maximum number of files allowed. 0 means unlimited, -1 included in user quota
-
-For example if you configure `/tmp/mapped` or `C:\mapped` as mapped path and `/vfolder` as virtual path then SFTP/SCP users can access the mapped path via the `/vfolder` SFTP path.
-
-The same virtual folder, identified by the `mapped_path`, can be shared among users and different folder quota limits for each user are supported.
-Folder quota limits can also be included inside the user quota but in this case the folder is considered "private" and sharing it with other users will break user quota calculation.
-
-You don't need to create virtual folders, inside the data provider, to associate them to the users: any missing virtual folder will be automatically created when you add/update a user. You only have to create the folder on the filesystem.
-
-Using the REST API you can:
-
-- monitor folders quota usage
-- scan quota for folders
-- inspect the relationships among users and folders
-- delete a virtual folder. SFTPGo removes folders from the data provider, no files deletion will occur
-
-If you remove a folder, from the data provider, any users relationships will be cleared up. If the deleted folder is included inside the user quota you need to do a user quota scan to update its quota. An orphan virtual folder will not be automatically deleted since if you add it again later then a quota scan is needed and it could be quite expensive, anyway you can easily list the orphan folders using the REST API and delete them if they are not needed anymore.
-
-Overlapping virtual paths are not allowed for the same user, overlapping mapped paths are allowed only if quota tracking is globally disabled inside the configuration file (`track_quota` must be set to `0`).
-Virtual folders are supported for local filesystem only.

-# WebDAV
-
-The experimental `WebDAV` support can be enabled by setting a `bind_port` inside the `webdavd` configuration section.
-
-Each user has his own path like `http/s://<SFTPGo ip>:<WevDAVPORT>/<username>` and it must authenticate using password credentials.
-
-WebDAV is quite a different protocol than SCP/FTP, there is no session concept, each command is a separate HTTP request and must be authenticated, to improve performance SFTPGo caches authenticated users. This way SFTPGo don't need to do a dataprovider query and a password check for each request.
-
-The user caching configuration allows to set:
-
-- `expiration_time` in minutes. If a user is cached for more than the specified minutes it will be removed from the cache and a new dataprovider query will be performed. Please note that the `last_login` field will not be updated and `external_auth_hook`, `pre_login_hook` and `check_password_hook` will not be executed if the user is obtained from the cache.
-- `max_size`. Maximum number of users to cache. When this limit is reached the user with the oldest expiration date will be removed from the cache. 0 means no limit however the cache size cannot exceed the number of users so if you have a small number of users you can set this value to 0.
-
-Users are automatically removed from the cache after an update/delete.
-
-WebDAV protocol requires the MIME type for each file. SFTPGo will first try to guess the MIME type by extension. If this fails it will send a `HEAD` request for Cloud backends and, as last resort, it will try to guess the MIME type reading the first 512 bytes of the file. This may slow down the directory listing, especially for Cloud based backends, if you have directories containing many files with unregistered extensions. To mitigate this problem, you can enable caching of MIME types so that the MIME type detection is done only once.
-
-The MIME types caching configurations allows to set the maximum number of MIME types to cache. Once the cache reaches the configured maximum size no new MIME types will be added. The MIME types cache  is a non-persistent in-memory cache. If you need a persistent cache add your MIME types to `/etc/mime.types` on Linux or inside the registry on Windows.
-
-WebDAV should work as expected for most use cases but there are some minor issues and some missing features.
-
-Know issues:
-
-- removing a directory tree on Cloud Storage backends could generate a `not found` error when removing the last (virtual) directory. This happens if the client cycles the directories tree itself and removes files and directories one by one instead of issuing a single remove command
-- the used [WebDAV library](https://pkg.go.dev/golang.org/x/net/webdav?tab=doc) asks to open a file to execute a `stat` and sometimes reads some bytes to find the content type. Stat calls are executed before and after a download too, so to be able to properly list a directory you need to grant both `list` and `download` permissions and to be able to upload files you need to gran both `list` and `upload` permissions
-- the used `WebDAV library` not always returns a proper error code/message, most of the times it simply returns `Method not Allowed`. I'll try to improve the library error codes in the future
-- if an object within a directory cannot be accessed, for example due to OS permissions issues or because is a missing mapped path for a virtual folder, the directory listing will fail. In SFTP/FTP the directory listing will succeed and you'll only get an error if you try to access to the problematic file/directory
-
-We plan to add [Dead Properties](https://tools.ietf.org/html/rfc4918#section-3) support in future releases. We need a design decision here, probably the best solution is to store dead properties inside the data provider but this could increase a lot its size. Alternately we could store them on disk for local filesystem and add as metadata for Cloud Storage, this means that we need to do a separate `HEAD` request to retrieve dead properties for an S3 file. For big folders will do a lot of requests to the Cloud Provider, I don't like this solution. Another option is to expose a hook and allow you to implement `dead properties` outside SFTPGo.
