I just recently purchased a ALFA AWUS036H wireless usb adapter from Amazon. My purpose is to learn how to crack WPA2-PSK wireless encryption for educational purposes. I have my A+,Security+,Network+ and Microsoft MCP certifications and i want to brush up on wireless encryption. I am no stranger to wireless encryption penetration testing as i have cracked WEP, years ago via Back Track Live CD and on windows via Dos box using the Air-crack suite. I did attempt to crack WPA back then, the farthest i have gotten was the 3 way hand shake, via air-crack suite on windows ( didn't know much about dictionary files and brute force methods at the time.) ^_^ I know i will receive lots of assistance and advice on this site, being it seems full of knowledgeable, brethren. ^_^
