How to install Pyrit in Kali Linux?

This guide (How to install Pyrit in Kali Linux) is part of a series that guides readers on How to install FGLRX, AMD APP SDK, CAL++ and Pyrit in Kali Linux. The idea is to install correct drivers in Kali Linux for your GPU and use CPU+GPU combination with Pyrit to make raw data crunching faster. An example would be to utilize this combined processing power to crunch though WPA/WPA2 capture file to find Wifi password.

Check FGLRX Installation

First check if fglrx module is installed:

lsmod | grep fglrx

You should get a response similar to:

fglrx 2635205 82
button 12945 1 fglrx

If not installed follow this guide to install it.

Check AMD APP SDK Installation

Check if AMD APP SDK is installed. If not installed, follow this guide to install it.

Check CAL++ Installation

Check if CAL++ is installed. If not installed, follow this guide to install it.

Why Pyrit?

Pyrit allows to create massive databases, pre-computing part of the IEEE 802.11 WPA/WPA2-PSK authentication phase in a space-time-tradeoff. Exploiting the computational power of Many-Core- and other platforms through ATI-Stream, Nvidia CUDA, OpenCL and VIA Padlock, it is currently by far the most powerful attack against one of the world’s most used security-protocols.

Install Pyrit in Kali

Install prerequisites

apt-get install libpcap-dev

Remove existing installation of pyrit

apt-get remove --purge pyrit

If you are not using a clean install of Kali (not recommended), you may need to issue the following command:

rm -r /usr/local/lib/python2.7/dist-packages/cpyrit/

Download pyrit

svn checkout http://pyrit.googlecode.com/svn/trunk/ pyrit_svn

Install Pyrit

cd pyrit_svn/pyrit/
./setup.py build install

Install CAL++ plugin

cd ../cpyrit_calpp/

Edit setup.py

Edit setup.py file and modify/replace the followings:
find VERSION = '0.4.0-dev' and replace with VERSION = '0.4.1-dev'
find CALPP_INC_DIRS.append(os.path.join(CALPP_INC_DIR, 'include')) and replace with

CALPP_INC_DIRS.append(os.path.join(CALPP_INC_DIR, 'include/CAL'))

 

Save and quit, then issue the following command:

 

./setup.py build install

 

There will be several warnings, but hopefully no errors and everything will be installed.

Test cpyrit
