Hum.. not sure what you want to do.. Do you want to encrypt the files, or
simply protect the passwords when using ftp ?

Anyway, I think an ssh tunel could do the trick: if you forward any
unpriviledged port to port 21 of the server, you will encrypt username and
password, but because the data go to port 20, they won't be encrypted.

On the client side you would do 
ssh -L 1234:ftp-server-name:21 localhost
(not need to be localhost though)

and again on the client, use any ftp client and connect to localhost
on port 1234. 

Only problem, you need an ftp server which allows passive mode, I think
wu-ftpd (default on lots of linux boxes) does not.

Anyone knows whether sftp encrypts the data or not ?

Thomas.
