This way not only does the "system", or anyone able to access it, not know what the password is, but the passwords used to login are tested "just-in-time" and then vanish. That's nice because you can't login with just the hashcode and you can't find the source of the hash from the hash itself since it is not an encoding, it is just a mapping from a big number space to a smaller number space - a destructive mapping. Still, it is possible to create a hash dictionary of "easy" passwords and then compare them to the known hash value for a match.
