By default this will serve files without needing a login.

|
|
You can either use an htpasswd file which can take lots of users, or
|
|
set a single username and password with the ` + "`--{{ .Prefix }}user` and `--{{ .Prefix }}pass`" + ` flags.
|
|
|
|
If no static users are configured by either of the above methods, and client
|
|
certificates are required by the ` + "`--client-ca`" + ` flag passed to the server, the
|
|
client certificate common name will be considered as the username.
|
|
|
|
Use ` + "`--{{ .Prefix }}htpasswd /path/to/htpasswd`" + ` to provide an htpasswd file. This is
|
|
in standard apache format and supports MD5, SHA1 and BCrypt for basic
|
|
authentication. Bcrypt is recommended.
|
|
|
|
To create an htpasswd file:
|
|
|
|
touch htpasswd
|
|
htpasswd -B htpasswd user
|
|
htpasswd -B htpasswd anotherUser
|
|
|
|
The password file can be updated while rclone is running.
|
|
|
|
Use ` + "`--{{ .Prefix }}realm`" + ` to set the authentication realm.
|
|
|
|
Use ` + "`--{{ .Prefix }}salt`" + ` to change the password hashing salt from the default.
|
|
|
