Best Configuration for optimal cracking

[macdonald]

WPA is not LM or NTLM. What you are asking is practically impossible. You would need 2,362,609 Radeon 7970 GPUs to brute force WPA length 8 in less than 6 hours. And as brute force has exponential time complexity, you would need 570x more 7970s to brute force length 9.

Thanks for the reply. My next question would then be, how to make a "reasonable" cracking system? Is the tool only efficient if we crack against a predetermined list of 'popular' passwords? I am sorry but I am just trying to understand the usage scenario of OCL hashcat plus.

Thanks again
