How to Use Public Key Authentication with SFTP Server

Can you please provide an example of how public key authentication works with sftp server? I'm guessing something like: ``` server.PreAuthentication = ServerOnPreAuthentication; private static void ServerOnPreAuthentication(object sender, PreAuthenticationEventArgs e) { e.Accept(AuthenticationMethods.PublicKey); } ``` And then maybe something like this: ``` server.Authentication = ServerOnAuthentication; private static void ServerOnAuthentication(object sender, AuthenticationEventArgs e) { if (e.Key.???) { var user = AddUser((SftpSshServer)sender, e.UserName, e.Password, userPath); e.Accept(user); } else { e.Reject(); } } ``` The problem is e.Key is always null for me, no matter what I do. I am testing this with FileZilla and a Logon Type of Key file where I specify a ppk file.

You need to set the allowed authentication methods in `AllowedAuthenticationMethods` in `ServerConfig` to public/private key only. That config instance can be accessed from `SshServerCore.Config`.
