Introduction

Aircrack-ng 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, as well as the all-new PTW attack, thus making the attack much faster compared to other WEP cracking tools. In fact, Aircrack-ng is a set of tools for auditing wireless networks.

What is Aircrack-ng ?

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

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
