Encrypt data! ;)
crypt is a one-way finction, it produces a hash from some
plain text, and its result is suitable to store sensitive
data in database, like passwords...
If you want to store information that you want to get back to
the initial state (plain text) you should not use crypt() or
md5()...
If you only want to store encrypted passwords crypt is enought..
When you want to confirm that a inputed text is equals to the
stored and encrypted password, you just have to encrypt the inputed text
and compare it with the previously stored password...
