Hi
you should compare password after receiving password from database and decode it with the algorathem. Now it will be in the text form. After that you can store this in the string and can use equals method of string class.

There's no reason to decode an encrypted password; simple encrypt two passwords
and if the encrypted passwords are equal, (most likely) the passwords themselves
are equal as well. It's called 'one way encryption'.
