Aircrack-ng is a complete suite of tools to assess WiFi network security.

It focuses on different areas of WiFi security:

• Monitoring: Packet capture and export of data to text files for further processing by third party tools.
• Attacking: Replay attacks, deauthentication, fake access points and others via packet injection.
• Testing: Checking WiFi cards and driver capabilities (capture and injection).
• Cracking: WEP and WPA PSK (WPA 1 and 2).

All tools are command line which allows for heavy scripting. A lot of GUIs have taken advantage of this feature. It works primarily Linux but also Windows, OS X, FreeBSD, OpenBSD, NetBSD, as well as Solaris and even eComStation 2.

• Autoconf
• Automake
• Libtool
• shtool
• OpenSSL development package or libgcrypt development package.
• Airmon-ng (Linux) requires ethtool.
• On windows, cygwin has to be used and it also requires w32api package.
• On Windows, if using clang, libiconv and libiconv-devel
• Linux: LibNetlink 1 or 3. It can be disabled by setting the flag 'libnl' to false.
• pkg-config (pkgconf on FreeBSD)
• FreeBSD, OpenBSD, NetBSD, Solaris and OS X with macports: gmake
• Linux/Cygwin: make and Standard C++ Library development package (Debian: libstdc++-dev)

• If you want SSID filtering with regular expression in airodump-ng (-essid-regex) pcre development package is required.
• 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)
• If you want to use Airpcap, the 'developer' directory from the CD is required.
• For best performance on FreeBSD (50-70% more), install gcc5 via: pkg install gcc5 Then compile with: gmake CC=gcc5 CXX=g++5
• rfkill

Below are instructions for installing the basic requirements to build aircrack-ng for a number of operating systems.

Cygwin requires the full path to the setup.exe utility, in order to automate the installation of the necessary packages. In addition, it requires the location of your installation, a path to the cached packages download location, and a mirror URL.

An example of automatically installing all the required dependencies is as follows:

c:\cygwin\setup-x86.exe -qnNdO -R C:/cygwin -s http://cygwin.mirror.constant.com -l C:/cygwin/var/cache/setup -P autoconf -P automake -P bison -P gcc-core -P gcc-g++ -P mingw-runtime -P mingw-binutils -P mingw-gcc-core -P mingw-gcc-g++ -P mingw-pthreads -P mingw-w32api -P libtool -P make -P python -P gettext-devel -P gettext -P intltool -P libiconv -P pkg-config -P git -P wget -P curl -P libpcre-devel -P openssl-devel -P libsqlite3-devel

sudo apt install build-essential autoconf automake libtool pkg-config libnl-3-dev libssl-dev libpcre3-dev ethtool shtool

pkg install autoconf automake libtool pkgconf sqlite3 git python3`

pacman -Sy autoconf automake1.15 libtool msys2-w32api-headers msys2-w32api-runtime pkg-config git python openssl-devel openssl libopenssl msys2-runtime-devel gcc binutils make pcre-devel libsqlite-devel

To build aircrack-ng, the Autotools build system is utilized. Autotools replaces the older method of compilation.

NOTE: If utilizing a developer version, eg: one checked out from source control, you will need to run a pre-configure script. The script to use is one of the following: autoreconf -i or env NOCONFIGURE=1 ./autogen.sh.

First, ./configure the project for building with the appropriate options specified for your environment:

./configure <options>

TIP: If the above fails, please see above about developer source control versions.

Next, compile the project (respecting if make or gmake is needed):

• Compilation:

  make

• Compilation on *BSD or Solaris:

  gmake

Finally, the additional targets listed below may be of use in your environment:

• Execute all unit testing:

  make check

• Strip debugging symbols:

  make strip

• Installing:

  make install

• Uninstall:

  make uninstall

When configuring, the following flags can be used and combined to adjust the suite to your choosing:

• with-airpcap=DIR: needed for supporting airpcap devices on windows (cygwin or msys2 only) Replace DIR above with the absolute location to the root of the extracted source code from the Airpcap CD or downloaded SDK available online.

• with-experimental: needed to compile tkiptun-ng, easside-ng (and buddy-ng) and wesside-ng. Building besside-ng-crawler requires LibPCAP (development package). On debian based distro, install libpcap-dev

• with-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.

• with-gcrypt: Use libgcrypt crypto library instead of the default OpenSSL. And also use internal fast sha1 implementation (borrowed from GIT) Dependency (Debian): libgcrypt20-dev

• with-duma: Compile with DUMA support. DUMA is a library to detect buffer overruns and under-runs. Dependencies (debian): duma

• with-xcode: Set this flag to true to compile on OS X with Xcode 7+.

• Configure and compiling:

  ./configure --with-experimental
  make
  

• Compiling wth gcrypt:

  ./configure --with-gcrypt
  make
  

• Installing:

  make install

• Installing, with external scripts:

  ./configure --with-experimental --with-ext-scripts
  make
  make install
  

• Testing (with sqlite, experimental and pcre)

  ./configure --with-experimental
  make
  make check
  

• Compiling on OS X with macports (and all options):

  ./configure --with-experimental
  gmake
  

• Compiling on OS X 10.10 with XCode 7.1 and Homebrew:

  env CC=gcc-4.9 CXX=g++-4.9 ./configure
  make
  make check
  

  NOTE: Older XCode ships with a version of LLVM that does not support CPU feature detection; which causes the ./configure to fail. To work around this older LLVM, it is required that a different compile suite is used, such as GCC or a newer LLVM from Homebrew.

  If you wish to use OpenSSL from Homebrew, you may need to specify the location to its' installation. To figure out where OpenSSL lives, run:

  brew --prefix openssl

  Use the output above as the DIR for --with-openssl=DIR in the ./configure line:

  env CC=gcc-4.9 CXX=g++-4.9 ./configure --with-openssl=DIR
  make
  make check
  

• Compiling on FreeBSD with better performance

  env CC=gcc5 CXX=g++5 ./configure
  gmake
  

Automatic detection of CPU optimization is done at run time. This behavior is desirable when packaging Aircrack-ng (for a Linux or other distribution.)

Also, in some cases it may be desired to provide your own flags completely and not having the suite auto-detect a number of optimizations. To do this, add the additional flag --without-opt to the ./configure line:

./configure --without-opt

Typically, the full path that is compiled in to the aircrack-ng binary is /usr/libexec/aircrack-ng. However, during development and/or packaging, it may be of use to specify a path that is dynamic in nature.

The environment variable AIRCRACK_LIBEXEC_PATH may be used to specify the location of the SIMD-optimized binaries. An example of such use is as follows:

env AIRCRACK_LIBEXEC_PATH=/home/user/dev/aircrack-ng/src ./src/aircrack-ng

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

• 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
