adding two dictionary words and a number, yeah, that helps a lot. looks like you are right, and that if your users use 2 words and a number, and you use a hash that takes 50ms to calculate, you are probably OK.

but my point is that passwords are a lot less secure than they sound if you just add up the characters. And most hash functions take a whole lot less than 50ms of cpu time to calculate. Bcrypt does look pretty cool in it's ability to slow down brute force attacks. It does still require a minimum amount of entropy in the user passwords, though.
