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.

If you are impatient and want to know how to get started, jump to the Getting Started Tutorial.

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
• More OS and platforms supported
• New WEP attack: PTW
• WEP dictionnary attack
• Fragmentation attack
• Improved cracking speed
• Capture with multiple cards
• New tools: airtun-ng, packetforge-ng (improved arpforge), wesside-ng, easside-ng, airserv-ng, airolib-ng, airdriver-ng and airbase-ng
• Optimizations, other improvements and bug fixing
• …

Note: Check trac for planned and requested features

Latest version: 1.0-beta2

• Linux (Driver patches)
• Zaurus (1.0-dev r830; older than beta2)

IMPORTANT Information Regarding Windows Version IMPORTANT
The windows version requires you to develop your own DLLs to link aircrack-ng to your wireless card. The required DLLs are not provided in the download nor available anywhere on the Internet. Without these DLLs, the windows version will not function. Do NOT post questions or problems to the forum regarding the windows version. At present, there is no support provided.

• I have read the above limitations and still wish to download the Windows version

• Installing the aircrack-ng suite and the drivers
• Bugs
