Using a Clear Command Channel with SSL

Using CCC (Clear Command Channel), your connection and login are encrypted, but when you begin transferring data, all FTP commands are sent in clear text. The data transfers remain encrypted, unless you choose to use a clear data channel. SSL connections require CCC when connecting in PORT mode from behind a NAT firewall.

The Clear Command channel option is only available with SSL connections.
