No idea what you are talking about. ssh encrypts everything passing between
the two computers.

We're talking about SFTP, which is a variant how to use SSH to secure the
FTP protocol. In the SFTP setup, the protection by SSH is only applied to
the data transfer channel.

Do you have any URL to some documentation of this "SFTP" protocol? I
have just checked with my ssh sftp client and a network sniffer: There
is nothing transferred unencrypted. Everything goes through the SSH
tunnel. So maybe different people called different protocols SFTP at
times. However, I have never heard of an FTP protocol which encrypts
only the data traffic and not the command channel. It would be good if
you provided some link. That would be interesting.

We have to find out what "SSH/SFTP" in Core FTP really does. But the
label to me says it does what the ssh sftp client does which is not
what you wrote.
