Actually from past some days I am trying to crack wpa2 using bruteforce attack. I researched on the subject and find that only brute force attack can crack wpa1 encryption. You can speed up the process by using rainbow tables. Is there any tool to create our own rainbow table as the ESSID that I am trying to crack is not default one. I am able to find the torrent that has precomputed rainbow tables but my ESSID is not in there list. So is there any better way to crack WPA2 then I am trying to do. Or if not then how can I generate my own rainbow table to crack the same.
