Very interesting - thanks. You'd still have to crack each password individually though, right? i.e. for row 1 I would need to try X passwords from my password

Very interesting - thanks. You'd still have to crack each password individually though, right? i.e. for row 1 I would need to try X passwords from my password dictionary, and for each of the attempts bcrypt the guess with the given salt and check to see if worked, and then repeat that for each row individually, rather than checking every row simultaneously.
