SSL Options
ssl_enable

If enabled, and vsftpd was compiled against OpenSSL, vsftpd will support secure connections via SSL.

This applies to the control connection (including login) and also data connections. You'll need a client with SSL support too.

NOTE!! Beware enabling this option. Only enable it if you need it. vsftpd can make no guarantees about the security of the OpenSSL libraries.

By enabling this option, you are declaring that you trust the security of your installed OpenSSL library.
