NIST Post-Quantum Cryptography Project
The standardisation programme behind FIPS 203, 204 and 205, and the ongoing selection rounds.
Why this is listed
It publishes the normative documents themselves, FIPS 203, 204 and 205, and still runs the selection rounds that are meant to produce further signatures.
NIST's post-quantum project ran the competition that produced the algorithms now published as FIPS 203 (ML-KEM), FIPS 204 (ML-DSA) and FIPS 205 (SLH-DSA), and continues to run selection rounds for additional signatures.
It is the primary source for what the standards actually require. Our own standards pages explain what those requirements mean in practice; they are not a substitute for reading the documents.
