Now comes the luck part of this all. Luck you ask? 'But I am a l33t h4x0r!! This should not be a matter of luck!?' Well, to a large extent it is, and this is the reason. The syskey is what the OS uses to generate the password hash, as we have said. In windows xp, the algorithm used is one-way, meaning you can't take the hash, put it through some 'reverse-algorithm', and get the original password out. In addition, in windows xp, the passwords are stored as two different types of hashes, an lmhash), and an nthash. For reasons well beyond the scope of this document, nthashes are much harder to crack. The main reason for this is that lmhashes are old and crappy (used in much earlier OS's for network authentication). That said, the way third party programs go about cracking the hash is they try every single letter/number/symbol combination to various lenghts, and send that through that same algorithm your OS uses to create the real hash. Once there is a match, you have the password. The downside to this method is inherent from virtually limitless possibilities for passwords. A password of 10 characters has (assuming the password is alphanumeric) roughly 36 * 36 * 36 * 36 * 36 * 36 * 36 * 36 * 36 * 36, or 36^10, or 3,656,158,440,062,976 possibilities. Even if you have a really good computer, its still gonna take a long ass time, unless you're lucky. The user interface of these programs is pretty straight foward: You input the SYSKEY, Open up the SAM, and let it crank. New computers using HT (hyper-threading[intels] or hyper-transport[amds]) can crunch roughly 6 billion operations per second. The number mentioned above, for a 10 digit password, is in the quadrillions would take a processor 1015.5 hours or 42 days of straight computation to get the the last possible password. That is the reason why you hope to be lucky and end up with a modest 5 or 6 digit password.
