As youcan see this simple dictionary attack took 51 seconds, we can speed upthis process by precomputing the WPA-PMK to crack the WPA-PSK (seebelow).

genpmkis used to precompute the hash files in a similar way to Rainbow tablesis used to pre-hash passwords in Windows LANMan attacks. There is aslight difference however in WPA in that the SSID of the network isused as well as the WPA-PSK to "salt" the hash. This means that weneed a different set of hashes for each and every unique SSID i.e. aset for "linksys" a set for "tsunami" etc.

So to generate some hash files for a network using the SSID cuckoo we use:

Now wehave created our hash file we can use it against any WPA-PSK networkthat is utilising a network SSID of cuckoo. Remember the capture(wpa-test-01.cap) must contain the four-way handshake to be successful.: D; y: N6 D J. O+ Z7 N$ J* V

However, precomputing large hashfiles for common SSIDS (e.g. linksys, tsunami) would be a sensible movefor most penetration testers.
