Hi, I am having a discussion with co-worker about an old video on here about cracking the WPA PSK TKIP passphrase. The 4 way handshake was captured (which I believe is a weakness in WPA correct?) and a dictionary attack was used to get the passphrase "starwars". Could this same thing be done with AES? Could you not just substitute using the TKIP algorithm with the AES one? Also could you not still capture the 4 way handshake? Thanks Rich
