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

Getting some decent computing power (try looking into clustering) and 
generating your own rainbow table (perhaps from your own wordlist) should be 
faster then brute forcing. and it's easier too because afaik there's no way to 
easily set up multiple pc's to brute force it. (but perhaps i'm overlooking 
something)

  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.

    How long could Jacktheripper take to crack WPA?

    Is it possible to capture a handshake, how many handshake could you need?
