(http://www.churchofwifi.org/Project_Display.asp?PID=95), then. 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.
