1. Executive Summary Pyrit is a powerful open-source tool for attacking the IEEE 802.11 WPA/WPA2-PSK authentication protocol. It is best known for its ability to perform massive pre-computation of WPA handshakes using various computing hardware, including GPUs (via CUDA/OpenCL) and multiple CPUs. This report provides a comprehensive guide to installing Pyrit on Kali Linux, covering dependencies, installation methods, hardware acceleration, and troubleshooting.

The repo version is often compiled without CUDA/OpenCL and may be several versions behind. 3.2 Method 2: Compiling from Source (Recommended for Full Features) This method provides the latest version with GPU acceleration. Step 1: Install Build Dependencies sudo apt install -y git gcc python3-dev python3-setuptools libssl-dev libpcap-dev Step 2: Install Optional GPU Libraries For NVIDIA CUDA:

sudo apt install -y opencl-headers ocl-icd-libopencl1 git clone https://github.com/JPaulMora/Pyrit.git cd Pyrit sudo python3 setup.py install Step 4: Install pyrit-cli (Command Line Interface) cd pyrit-cli sudo python3 setup.py install 4. Post-Installation Configuration 4.1 Verify Installation pyrit list_cores Expected output shows detected CPU cores and GPU devices. 4.2 Test GPU Acceleration pyrit benchmark This runs performance tests. CUDA/OpenCL devices appear if correctly configured. 4.3 System Path Issues If pyrit command is not found after source install, add to PATH:

sudo apt install -y nvidia-cuda-toolkit

sudo apt install pyrit -y pyrit --version
