>>MD5 and SHA are by their very nature one way encryption. You cannot
decrypt them.
Indeed, the point of these algorithms is to sign data (like a
fingerprint).
In order to encrypt you may go for Symmetrical algos (AES, 3DES ....with
those, the key must be known on both sides of the pipe) or Asymmetrical
(RSA ... - where you get a private key on one side and a public key on
the other - good but slow).
Often you find hybrid methods: you start your session with a
public/private style method just to exchange a symmetrical key that
you'll use for the rest of the session.

Philippe
