Report Offensive Message

I just read an article on WPA/WPA2 cracking that suggests recovering the PSK is not as impossible as it firswt seems.

Now maybe im just missing something, and yes I realize that the demo used an 8 character PSK & not the 10 character you are recommending, but if the PSK is within a dictionary (and alot probably are) then cracking the key apparently has become much faster.. Youre thoughts on this would be appreciated.
