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

Thanks Adese. Yes bruteforce attack against a WPA are only posible when the key 
is no more than 8, and then only if they aren´t very imaginative.

I have the possibility of capturing handshakes and there seems to be a few 
everyday, does aircrack support doing this?

Where can I get a detailed information of the airodump, aircrack and air replay 
functions?

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?
