@ -136,7 +136,7 @@ The configuration file contains the following sections:
  - `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.
  - `host_certificates`, list of strings. Public host certificates. Each certificate can be defined as a path relative to the configuration directory or an absolute one. Certificate's public key must match a private host key otherwise it will be silently ignored. Default: empty.
  - `host_key_algorithms`, list of strings. Public key algorithms that the server will accept for host key authentication. The supported values are: `rsa-sha2-512-cert-v01@openssh.com`, `rsa-sha2-256-cert-v01@openssh.com`, `ssh-rsa-cert-v01@openssh.com`, `ssh-dss-cert-v01@openssh.com`, `ecdsa-sha2-nistp256-cert-v01@openssh.com`, `ecdsa-sha2-nistp384-cert-v01@openssh.com`, `ecdsa-sha2-nistp521-cert-v01@openssh.com`, `ssh-ed25519-cert-v01@openssh.com`, `ecdsa-sha2-nistp256`, `ecdsa-sha2-nistp384`, `ecdsa-sha2-nistp521`, `rsa-sha2-512`, `rsa-sha2-256`, `ssh-rsa`, `ssh-dss`, `ssh-ed25519`. Default values: `rsa-sha2-512-cert-v01@openssh.com`, `rsa-sha2-256-cert-v01@openssh.com`, `ecdsa-sha2-nistp256-cert-v01@openssh.com`, `ecdsa-sha2-nistp384-cert-v01@openssh.com`, `ecdsa-sha2-nistp521-cert-v01@openssh.com`, `ssh-ed25519-cert-v01@openssh.com`, `ecdsa-sha2-nistp256`, `ecdsa-sha2-nistp384`, `ecdsa-sha2-nistp521`, `rsa-sha2-512`, `rsa-sha2-256`, `ssh-ed25519`.
-  - `moduli`, list of strings. Diffie-Hellman moduli files. Each moduli file can be defined as a path relative to the configuration directory or an absolute one. If set, `diffie-hellman-group-exchange-sha256` and `diffie-hellman-group-exchange-sha1` KEX algorithms will be available, `diffie-hellman-group-exchange-sha256` will be enabled by default if you don't explicitly set KEXs. Default: empty.
+  - `moduli`, list of strings. Diffie-Hellman moduli files. Each moduli file can be defined as a path relative to the configuration directory or an absolute one. If set and valid, `diffie-hellman-group-exchange-sha256` and `diffie-hellman-group-exchange-sha1` KEX algorithms will be available, `diffie-hellman-group-exchange-sha256` will be enabled by default if you don't explicitly set KEXs. Invalid moduli file will be silently ignored. Default: empty.
  - `kex_algorithms`, list of strings. Available KEX (Key Exchange) algorithms in preference order. Leave empty to use default values. The supported values are: `curve25519-sha256`, `curve25519-sha256@libssh.org`, `ecdh-sha2-nistp256`, `ecdh-sha2-nistp384`, `ecdh-sha2-nistp521`, `diffie-hellman-group14-sha256`, `diffie-hellman-group16-sha512`, `diffie-hellman-group18-sha512`, `diffie-hellman-group14-sha1`, `diffie-hellman-group1-sha1`. Default values: `curve25519-sha256`, `curve25519-sha256@libssh.org`, `ecdh-sha2-nistp256`, `ecdh-sha2-nistp384`, `ecdh-sha2-nistp521`, `diffie-hellman-group14-sha256`. SHA512 based KEXs are disabled by default because they are slow. If you set one or more moduli files,  `diffie-hellman-group-exchange-sha256` and `diffie-hellman-group-exchange-sha1` will be available.
  - `ciphers`, list of strings. Allowed ciphers in preference order. Leave empty to use default values. The supported values are: `aes128-gcm@openssh.com`, `aes256-gcm@openssh.com`, `chacha20-poly1305@openssh.com`, `aes128-ctr`, `aes192-ctr`, `aes256-ctr`, `aes128-cbc`, `aes192-cbc`, `aes256-cbc`, `3des-cbc`, `arcfour256`, `arcfour128`, `arcfour`. Default values: `aes128-gcm@openssh.com`, `aes256-gcm@openssh.com`, `chacha20-poly1305@openssh.com`, `aes128-ctr`, `aes192-ctr`, `aes256-ctr`. Please note that the ciphers disabled by default are insecure, you should expect that an active attacker can recover plaintext if you enable them.
  - `macs`, list of strings. Available MAC (message authentication code) algorithms in preference order. Leave empty to use default values. The supported values are: `hmac-sha2-256-etm@openssh.com`, `hmac-sha2-256`, `hmac-sha2-512-etm@openssh.com`, `hmac-sha2-512`, `hmac-sha1`, `hmac-sha1-96`. Default values: `hmac-sha2-256-etm@openssh.com`, `hmac-sha2-256`.

 ## Obtaining a certificate using the Lego CLI tool

@ -149,6 +149,8 @@ SFTPGO_ACME__HTTP01_CHALLENGE__WEBROOT="/var/www/sftpgo.com"
 Make sure that the `sftpgo` user can write to the `/var/www/sftpgo.com` directory or pre-create the `/var/www/sftpgo.com/.well-known/acme-challenge` directory with the appropriate permissions.
 This directory must be publicly served by your web server.

+:warning: in this example we assume you have an existing HTTP server. If not, you can leave the web root blank and SFTPGo will resolve the HTTP01 challenge by itself.

 Register your account and obtain certificates by running the following command.
