[kismac] Re: what is required to crack WPA?

One only needs 1 handshake that indeed "can be captured". like I said
earlier, it's captured when a client connects to an access point / router.

bruteforcing with JTR could take a very long time. refer to this :
http://lastbit.com/pswcalc.asp so you can start disappointing yourself.

this is why you should at least try a dictionary attack with a real big
wordlist before you try the lengthy task of bruteforcing.
