aircrack-ng is a set of tools for auditing wireless networks.
It's an enhanced/reborn version of aircrack. It consists of
airodump (an 802.11 packet capture program), aireplay (an 802.11
packet injection program), aircrack (static WEP and WPA-PSK
cracking), airdecap (decrypts WEP/WPA capture files), and some
tools to handle capture files (merge, convert, etc.).
