You won't get a decrypted password without doing a dictionary
check with cracklib or similar software as *nix passwords are
done with a one-way encryption.

Clear text passwords may be tested against the encrypted
passwords using the ``crypt(3)'' C routine (python and perl have
a scriptable interface to this).  In python this check might be:

	from crypt import crypt
	cryptpw == crypt(plaintext, cryptpw)
