Hacking wifi (WPA/WPA2)

Hacking WPA/WPA2 network is very harder than WEP. Aircrack-ng can only crack pre-shared keys. And WPA/WPA2 supports many types of authentication beyond pre-shared keys. You can crack the pre-shared key is if it is a Dictionary word or Relatively short in length.

So for hacking WPA/WPA2 wifi network, only one option is available is to use a Dictionary attack method. In this attack, the text file contains words and check whether it is password or not. This process takes very long time for find correct password but you can find wifi password only using this method.

You can download Dictionary attack list from google. There are lots of lists available on the internet you can download any list which one is large.
