Hello Rob,

But again, if you're using a known approved encryption, like bcrypt, and someone downloads the database, can't they just brute force it by hammering on bcrypt the same as brute force it by hammering on the sql function?

Yes, of course. Weak passwords from users stay weak passwords. Dictionary attacks are still possible: Trying out a large list of words and popular password strings (like the famous 12345) isn't hard.

Hashing instead of encryption prevents to recalculate the password from the string stored in the database, nothing more.
