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.* @( ~' }" l# h7 D* k! z

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