Re: Re[2]: [PHP] Credit Card suggestions

Makes sense, except if you use upper and lowercase characters, numbers, and symbols (as you should for secure passwords). I would think that with these kind of passwords, storing the sheer number of posibilites would get slightly large. And I mean even if it is easy to break, it's more secure then storing them clear text.
