# Compiling hashcat for Windows with Windows Subsystem for Linux.
# Compiling hashcat for Windows with Windows Subsystem for Linux 2.
Tested on Windows 10 x64, should also work to build hashcat for Windows on Linux.
Tested on Windows 11 x64, should also work to build hashcat for Windows on Linux.
I had it tested with WSL2 using Ubuntu_2004.2020.424.0_x64.appx.
I had it tested with WSL2 using "Ubuntu", which at the time of writing is Ubuntu 24.04
Make sure to have the system upgraded after install (otherwise it will fail to find the gcc-mingw-w64-x86-64 package).
### Installation ###
Enable WSL.
Enable WSL2.
Press the win + r key on your keyboard simultaneously and in the "Run" popup window type bash and make sure to install additional dependencies necessary for hashcat compilation
```bash
sudo apt install gcc-mingw-w64-x86-64 g++-mingw-w64-x86-64 make git
sudo apt install gcc-mingw-w64-x86-64 g++-mingw-w64-x86-64 make git zstd python3-dev
git clone https://github.com/hashcat/hashcat
git clone https://github.com/win-iconv/win-iconv
cd win-iconv/
cmake -D WIN_ICONV_BUILD_EXECUTABLE=OFF -D CMAKE_INSTALL_PREFIX=/opt/win-iconv-64 -D CMAKE_CXX_COMPILER=$(which x86_64-w64-mingw32-g++) -D CMAKE_C_COMPILER=$(which x86_64-w64-mingw32-gcc)
sudo make install
cd ../
wget https://repo.msys2.org/mingw/mingw64/mingw-w64-x86_64-python-3.12.10-1-any.pkg.tar.zst
sudo mkdir /opt/win-python
sudo tar --zstd -xf mingw-w64-x86_64-python-3.12.10-1-any.pkg.tar.zst -C /opt/win-python
