CryptoSys PQC
CryptoSys PQC provides support for all three NIST-approved Post Quantum Cryptography (PQC) algorithms:
- Module-Lattice-Based Key-Encapsulation Mechanism (ML-KEM) FIPS.203
- Module-Lattice-Based Digital Signature Algorithm (ML-DSA) FIPS.204
- Stateless Hash-Based Digital Signature Algorithm (SLH-DSA) FIPS.205
These are based on the original submitted algorithms
Kyber,
Dilithium and
SPHINCS+, respectively.
Features
- Interfaces for C#, VB.NET, C++ (STL), Python and ANSI C
- Support for all parameter sets of ML-KEM, ML-DSA and SLH-DSA algorithms
- Support for "pure" and "pre-hash" signature variants
- Support for "hedged" and deterministic signatures
- Support for "ExternalMu" variant for ML-DSA
- Support for both expanded and "seed" keys for ML-DSA and ML-KEM
- Full checking of expanded ML-KEM keys before use
- Built-in random number generator (RBG) designed to conform to NIST Special Publication 800-90.
- Ability to pass known random test values to compare with known test vectors
- Passes all test vectors provided by NIST at NIST Test Vectors
