NIST FIPS 203, 204 & 205 Compliance — What It Means for Your Business
The new NIST standards for post-quantum cryptography are now official. We explain what ML-KEM, ML-DSA, and SLH-DSA are, and how PosQuantum is ahead with SDKs ready in 14 languages.
In 2024, NIST (National Institute of Standards and Technology) published the first official standards for post-quantum cryptography: FIPS 203, FIPS 204, and FIPS 205. These standards define the algorithms that will protect the world’s data against the threat of quantum computers.
FIPS 203 (ML-KEM, based on Kyber) is the standard for Key Encapsulation Mechanism — the secure way to exchange cryptographic keys between two parties. FIPS 204 (ML-DSA, based on Dilithium) is the standard for digital signatures. FIPS 205 (SLH-DSA, based on SPHINCS+) offers a hash-based signature alternative as a backup.
PosQuantum has implemented all three standards in its PQSL (Post-Quantum Security Layer) library, available in 14 native SDKs: Python, Rust, Node.js, Go, Java, C#, Swift, Kotlin, C++, Ruby, PHP, Dart, Elixir, and Zig.
For your business, NIST compliance means being prepared for the regulatory requirements that are coming. Governments and major enterprises are already requiring post-quantum migration plans. Start today, before it becomes a last-minute obligation.
Integration with PQSL is straightforward: install the SDK in your project’s language, configure the desired security level, and all cryptographic operations automatically use post-quantum algorithms.
