Aircrack-ng

Introduction
aircrack is an 802.11 WEP and WPA-PSK keys cracking program that can recover keys once enough data packets have been captured. It implements the standard FMS attack along with some optimizations like KoreK attacks, thus making the attack much faster compared to other WEP cracking tools. In fact, aircrack is a set of tools for auditing wireless networks.


What is Aircrack-ng ?
Aircrack-ng is the next generation of aircrack with lots of new features:

* Better documentation (wiki, manpages) and support (Forum, trac, IRC: #aircrack-ng on Freenode).
* More cards/drivers supported
* New WEP attack: PTW
* More OS and plateforms supported
* Fragmentation attack
* Improved cracking speed
* WEP dictionnary attack
* Capture with multiple cards
* New tools: airtun-ng, packetforge-ng (improved arpforge), wesside-ng and airserv-ng
* Optimizations, other improvements and bug fixing
