This repository contains the reference implementation of the Dilithium Post Quantum Cryptography algorithms usable through Python Native Interface wrappers.

If you use Windows you should install MSYS2 and make several commands:

pacman -S --needed base-devel mingw-w64-i686-toolchain
pacman -S mingw-w64-x86_64-python3

mkdir build
cd build
cmake .. -G "MSYS Makefiles"
make

For make a Python wrapper in Linux you should use cmake:

mkdir build
cd build
cmake ..
make

The build result will be available in the /build directory. Or you can just open the project in Visual Studio and build it inside the IDE.

To use the Kyber functions in a PYTHON project, you must use shared libraries located in the /build directory. Insert Python module into your application and use necessary functions. Shared libraries should located in the same directory. For example:

import ctypes
import pydilithium;
...
a = ''
b = ''
c = POINTER(a);
d = POINTER(b);

pykyber.pqcrystals_dilithium2_ref_keypair(c, d)
print(a)
print(b)
}

The necessary shared libraries are placed in /build directory. It is not necessary to use all classes (with _aes and without). Just choose what you want to use.
