just did a litttle research there. UPC WPA keys consist of 8 random capital letters.
even with this restriction, that leaves 208,827,064,576 possible combinations (26^8),
that's a wordlist of 208GB using ASCII encoding.
using aircrack-ng it would take my new system, which is checking roughly 3,000
keys a second, 2.2 years to go thru every possible combination. i think i might take
a tea break while my PC is busy.
now if someone could port aircrack to use my GT200 GPU… ;-)
