Sorry to bug folks, but I just recently needed to learn about cracking. I have passwords from a system and the policy is 15 character, 1 upper, 1 lower, 1 number, 1 special character. They are salted md5 hashes. When I look at the math, this seems impossible. Would dictionaries make much of a difference with this sort of length or is this a completely losing situation?
