It's depends upon your needs, but if you're on a Unix system why not just
access the system crypt function. You could create a PostgreSQL C function
to easily access it. Just look in contrib for an example of the code.
If you're on a Windows system I'd say give up now unless you want to
implement the entire crypt trapdoor algorithms.
