This is a good tutorial, but I don't think anyone should use sha1

1. When using sha1() in MySQL, you're dealing with plain-text passwords in the queries which is NOT good.
2. If you've already hassled with setting up MySQL, then you might as well do whirlpool. In that case, you can avoid using plain-text passwords in queries.
3. Have you ever heard of password salting?
