wpa cracker

WPA Cracker is a cloud cracking service for penetration testers and network auditors who need to check the security of WPA-PSK protected wireless networks.

WPA-PSK networks are vulnerable to dic tionary attacks, but running a respectable-sized dictionary over a WPA network handshake can take days or weeks. WPA Cracker gives you access to a 400CPU cluster that will run your network capture against a 135 million word dictionary created specifically for WPA passwords. While this job would take over 5 days on a contemporary dual-core PC, on our cluster it takes an average of 20 minutes.

what dictionary use:
The standard English dictionary is 136 million words, and there is also an "extended" dictionary that is an additional 284 million words. The "extended" dictionary is not a superset of the "standard" dictionary. This is to say that the words in the "standard" dictionary are not also in the "extended" dictionary. The former contains the 136 million words that we find are most likely for cracking success, so we recommend only trying the "extended" dictionary where the "standard" dictionary has failed.
The job costs the same whether we find your password or not. You're paying for either the recovery (which is most often the case), or the knowledge that if you were to build an exhaustive 135 million word dictionary file and run your handshake against it for five days, you'd find nothing.
