The original poster said he couldn't figure out *how* passwords are encrypted, not how to decrypt them. I wouldn't trust a password encryption scheme that *relied* upon an attacker's inability to figure out *how* the encryption is done. You should *always* assume the enemy knows your encryption algorithm. Only the key is assumed secret. |> |>-- |>D'Arcy J.M.
