A note to the people who think that hashing a password multiple times makes it uncrackable:
It doesn't.
If you're using a standard hash cracker or rainbow tables, sure. But if you've got the
smarts to design your own hash cracker, you can just double-hash every string where it would
normally be hashed once, and then at best your hashes take twice as long to crack.
