I would like to turn off password authentication for SSH to my server, using keys instead. I don't see an option in Filezilla to use a public key though: is this not a feature of the SFTP spec?

1 - Have my ftp connections proxied to the outside via a script ( I can't find anywhere to do this ) 2 - Use the squid proxy for SFTP connections to the outside 3 - Able to operate in "hybrid-mode" ...
