And, just in case Darren's response is insufficient for your purposes.

Read up on RFC2228 - ftps - aka - FTP over TLS/SSL. 

sftp is Secure SSH's implementation of ftp, which runs over an SSH connection.
   From what I have found, it is still in IETF format.

Here's a little light reading to help, from someone who appears to be deeply 
involved in the ftps world.

Favorite comment from that page - "sftp is nothing to do with FTP over SSL, it 
is a way of doing file transfer over SSH which has nothing to do with FTP (RFC 
959)."

For info on the FTP over SSH (aka SFTP) read
http://www.ietf.org/internet-drafts/draft-ietf-secsh-filexfer-06.txt

Hope this helps.
