How To Install Pyrit In Kali Linux
Installing Pyrit on Kali Linux has become more complex recently because the tool was removed from official repositories. It primarily relies on Python 2, which has reached end-of-life, requiring manual installation from source or specialized scripts. Method 1: Installing from GitHub (Recommended)
This method involves cloning the repository and building it manually. It includes a "fudge" step to fix common AES compilation errors.
Update and Install DependenciesOpen your terminal and install the required development libraries:
sudo apt update -y sudo apt install git python2-dev libssl-dev libpcap-dev -y ``` Use code with caution. Copied to clipboard
Clone the RepositoryDownload the latest source code from the official GitHub mirror:
git clone https://github.com/JPaulMora/Pyrit.git --depth=1 cd Pyrit ``` Use code with caution. Copied to clipboard
Apply AES Fix and CompileTo avoid the common "COMPILE_AESNI" error during installation, run the following sequence:
sed -i "s/COMPILE_AESNI/COMPILE_AESNIX/" cpyrit/_cpyrit_cpu.c python2 setup.py clean python2 setup.py build sudo python2 setup.py install ``` Use code with caution. Copied to clipboard How to install Pyrit in Kali Linux
Verify the InstallationCheck if it’s working by displaying the help menu: pyrit -h ``` Use code with caution. Copied to clipboard Method 2: Automated Installation Script
If you are using a modern Kali Rolling release, you can use a pre-made bash script that handles all the "fudge" code and dependency issues automatically. Run via Curl:
curl https://raw.githubusercontent.com/Grezzo/pyrit-installer-for-kali-rolling/main/install-pyrit-kali-rolling-2021-1.sh | bash ``` Use code with caution. Copied to clipboard Common Troubleshooting
Missing pcap.h: This usually means libpcap-dev is not installed. Re-run sudo apt install libpcap-dev.
Command not found: Ensure you use python2 instead of python during the build process, as modern Kali defaults to Python 3.
Repository Errors: If apt update fails, ensure your /etc/apt/sources.list contains the official Kali repositories.
For high-speed cracking, you can also install the NVIDIA CUDA or OpenCL plugins after the main installation to utilize your GPU. Pyrit no longer working Kali Linux Rolling #589 - GitHub Installing Pyrit on Kali Linux has become more
Step 5: Verify Installation
Once installed, check if Pyrit recognizes your environment.
pyrit list_cores
If successful, you should see a list of your CPU cores ready to compute.
Important Legal & Ethical Notice
⚠️ Pyrit is a professional security testing tool. Only use it on:
- Networks you own
- Networks you have explicit written permission to test
- Your own lab environment
Unauthorized use of Pyrit against networks you don't own is illegal in most jurisdictions.
Step 4: Verify the Installation
pyrit --help
If you see the Pyrit banner and a list of commands, success!

How to Install Pyrit in Kali Linux
Because Pyrit is no longer in the default Kali repositories (and the legacy code often fails to compile on modern Python 3), you have to build it from source.
Note: This guide focuses on the CPU installation. GPU (CUDA/OpenCL) support requires specific proprietary drivers and proprietary compiler setups that are often broken on newer kernels. If successful, you should see a list of
Step 2: Clone the Pyrit Repository
git clone https://github.com/JPaulMora/Pyrit.git
cd Pyrit
For OpenCL support (AMD/Intel/NVIDIA)
sudo apt install -y opencl-headers ocl-icd-libopencl1 clinfo

Installing on modern Kali Linux is a common challenge for security enthusiasts, as the tool was officially removed from Kali’s repositories in 2020 due to its reliance on Python 2. However, you can still install it by compiling it from source. Kali Linux Package Tracker Important Note:

Pyrit was once a staple in the Kali Linux toolkit, famous for its ability to utilize GPU power to accelerate WPA/WPA2 cracking. While newer tools like Hashcat have largely taken its place, many legacy scripts and workflows still rely on it. Because it was removed from official repositories, we’ll walk through how to build it from the JPaulMora GitHub repository Step 1: Install Required Dependencies
Since Pyrit is built on Python 2, you need the legacy development files and specific libraries for packet capture and encryption. Open your terminal and run:
sudo apt update -y sudo apt install git python2-dev libssl-dev libpcap-dev python2 -y Use code with caution. Copied to clipboard Step 2: Clone the Pyrit Repository
