Aircrack-ng is an 802.11 WEP and WPA-PSK keys cracking program that can recover keys once enough data packets have been captured. The application works by implementing the standard FMS attack along with some optimizations such as KoreK attacks, as well as the PTW attack. This will then make the attack much faster compared to other WEP cracking tools.
Aircrack-ng is a set of tools for auditing wireless networks. The interface is standard and some command use skills will be required in order to operate this application.
Key new features include:
Better documentation and support.
More cards/drivers supported.
More OS and platforms supported.
WEP dictionary attack.
WPA Migration mode.
Improved cracking speed.
