I have finally made my wpacracker service public as well. With the recent release of another similar service I decided to implement mine as well. This one is GPU powered rather than cloud computing. This is NOT a guaranteed password crack or a bruteforce. Your cap file is tested against a 540 million word list optimized for WPA. There is a $10 charge however this is not to make money. The proceeds will go to the cost of a second box which will allow me the ability to double the speed of the cracker and also increase the size of the list.
