John is most certainly a fantastic candidate generator & hasher, but if you have any capture of the AP's traffic, you could reduce your search set considerably. Basic tenet of breaking cryptography: reduce your problem set. The more you know, the less work you have to do. Even a brute-force tool like John does this by being smart about hash implementations and character frequency analysis. You've already done so quite a bit if you are certain the key is 16 digits and numeric only. The Xeon 5160 I have could comfortably generate that search space in <5 days - while compute power may be a limiting factor, more limiting may be the method you're using to check each key. What are you using? Keep in mind, not sure anyone's said it, but 16^10 turns into roughly a terabyte of data. This is definitely doable with modern top-end hardware, but just so. -- To unsubscribe, e-mail john-users-unsubscribe@...ts.openwall.com and reply to the automated confirmation request that will be sent to you.
