rs.baselib.crypto.DummyPasswordHasher

All Implemented Interfaces:

ExtendedPasswordHasher, PasswordHasher

public class DummyPasswordHasher
extends Object
implements ExtendedPasswordHasher

A dummy implementation that actually does not hash any password but uses the plain password.

This implementation shall be used for fallback testing when no other hash algorithm fits. You should never use this class to actually hash passwords.
