Build Status Coverage Status

This directory contains our implementation of Kyber. Both the reference code and the AVX2 optimized code are in the directories ref/ and avx2/, respectively.


Also available is a highly portable cmake based build system that permits building the same sources into a summary library as well as all the same tests.

For fastest build performance, use of Ninja is recommended.

All tests can be run by invoking the (your-favourite-build-tool-command-here) test target.

Worked example

By calling

mkdir build-ninja && cd build-ninja && cmake -DBUILD_SHARED_LIBS=ON -GNinja .. && ninja && ninja test

the whole Kyber software family gets built in a highly portable as well as an avx2-optimized version, tested and delivered in a shared library.

For example, by running ./avx2/./avx2/test_speed512-90s_avx2 in the newly created 'build-ninja' folder, performance testing of Kyber512-90s in the optimized AVX2 variant is executed.

The resultant library might also be installed using the install target.

Note: Testing on Windows has only been done using MSVS 2015 (cl version 19) and msbuild.

You can’t perform that action at this time.
