QSC is a compact and self-contained post-quantum secure cryptographic library witten in C. It has been written to MISRA secure coding standards, and has been designed to be easy to read, verify, and implement. The code is well structured, readable and commented, and thoroughly documented, and this solution contains a testing platform, which provides various test functions for every primitive contained in the library. This library incorporates next-generation asymmetric and symmetric primitives, with a strong emphasis on true long-term security. The objective of this library is to provide a basis for future integration efforts, and as the foundation of a compact, high-security, post-quantum-secure communications platform. This version has been tested on Windows 10, Ubuntu Linux, and MAC Big Sur. This library has SIMD intrinsice integratewd throughout, using AVX, AVX2, and AVX512 implementations. This implementation uses a base reference code, or AVX/AVX2/AVX512 implementations of ciphers and cryptographic protocols. For best performance, set the project properties to the highest available SIMD instruction set supported by your CPU. AVX-512 instructions are fully supported in this implementation and offer the best performance profile.
