Aircrack is a suite of tools for 802.11a/b/g WEP and WPA cracking. It implements the best known cracking algorithms to recover wireless keys once enough encrypted packets have been gathered. . The suite comprises over a dozen discrete tools, including airodump (an 802.11 packet capture program), aireplay (an 802.11 packet injection program), aircrack (static WEP and WPA-PSK cracking), and airdecap (decrypts WEP/WPA capture files).

Wonderfully fast WEP cracker. Longest time it's ever taken me to crack a WEP with this is about 10 minutes. Fastest time with this tool was like 20 seconds. Cracking WPA is still a joke, expect months to years, even with the highest end of computers. Don't bother using is on windows though, it is made specifically for linux. You can buy a certain USB Wireless module that aircrack will work with for like 25 bucks, but not sure how well it works.
One of the quickest, one of the best. I use this tool suite almost daily, especially useful when traveling.
