WPA Encryption Cracking: Is it Possible ?

There are a few tools that can assist in a WPA-PSK crack. The first is KisMAC, however it is only useful to MAC users. Another is coWPATTY, which is a brute-force cracking tool that systematically attempts to crack the WPA-PSK by testing numerous passwords, in order, one at a time. Obviously this can be a time consuming process. This tool can only try 30-60 words per second with the possibilities are in the realm of 200 billion! Another tool is Aircrack, which can also capture data then perform a dictionary attack. Since this can be a time consuming process with a long enough pass phrase, which may deter crackers, I would recommend a pass phrase that is more then 20 characters and preferably not words that are found in the dictionary.
