Aircrack-ng

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.

It can attack WPA1/2 networks with some advanced methods or simply by brute force. It can also fully use a multiprocessor system to its full power in order to speed up the cracking process.

Building

Requirements

OpenSSL development package or libgcrypt development package
If you want to use airolib-ng and -r option in aircrack-ng, SQLite development package >= 3.3.17 (3.6.X version or better is recommended): libsqlite3-devel
On windows, cygwin has to be used and it also requires w32api and gcc-4 package.
If you want to use Airpcap, the 'developer' directory from the CD is required.

Compilating

Compilation:

make
Strip debugging symbols:

make strip
Installing:

make install
Uninstall:

make uninstall

Makefile flags

When compile and installing, the following flags can be used and combined to compile and install the suite:

sqlite: needed to compile airolib-ng and add support for airolib-ng databases in aircrack-ng. On cygwin: SQLite has to be compiled manually. See next section.
airpcap: needed for supporting airpcap devices on windows (cygwin only) REQUIREMENT: Copy 'developers' directory from Airpcap CD one level below this INSTALLING file Note: Not working yet.
experimental: needed to compile tkiptun-ng, easside-ng (and buddy-ng) and wesside-ng
ext_scripts: needed to build airoscript-ng, versuck-ng, airgraph-ng and airdrop-ng. Note: Experimental. Each script has its own dependences. Note: It's only required in install phase.
gcrypt: Use libgcrypt crypto library instead of the default OpenSSL. And also use internal fast sha1 implementation (borrowed from GIT)
libnl: Add support for netlink (nl80211). Linux only.
- Requires libnl1 OR libnl3.
- Dependencies (debian):
  - LibNL 1: libnl-dev
  - LibNL 3: libnl-3-dev and libnl-genl-3-dev.

Examples:

Compiling with sqlite and enabling experimental:

make sqlite=true experimental=true
Installing:

make sqlite=true experimental=true install
Installing, with external scripts:

make sqlite=true experimental=true ext_scripts=true
Compiling with gcrypt:

make gcrypt=true

Using precompiled binaries

Linux/BSD:

Use your package manager to download aircrack-ng
In most cases, they have an old version.

Windows:

Install the appropriate "monitor" driver for your card (standard drivers doesn't work for capturing data).
aircrack-ng suite is command line tools. So, you have to open a commandline Start menu -> Run... -> cmd.exe then use them
Run the executables without any parameters to have help
