There is no reason for you that you would want to decrypt the password.
If you want to make a login system, encrypt the stuff that player has input and compare it to the saved password.
Saving passwords in unencrypt format, or such hash formats as MD5 or SHA1 which provide a little bit better protection, but not by much.
Even guys at Adobe screwed up and had millions of user emails and passwords got into wrong hands...

So, be careful about passwords, and never store them in unencrypt state.
