FIPS Crypto Algorithms Implementation Hub

Navigate NIST FIPS algorithm standards for AES block encryption, Secure Hash Standard functions, SHA-3 and SHAKE functions, classical digital signatures, and post-quantum key establishment and signatures.

Use this hub to separate algorithm specifications from FIPS 140-3 module validation questions, then open the topic pages for implementation scope, validation evidence, and migration planning.

Map FIPS algorithm choices to validation evidence

Use this hub as the starting point for an algorithm inventory that distinguishes AES, hash, signature, KEM, and module-validation evidence instead of treating every cryptographic claim as one undifferentiated FIPS requirement.

What this unlocks
  • Identify where products use AES, SHA-2, SHA-3, DSS, ML-KEM, ML-DSA, or SLH-DSA and which FIPS publication supports each claim.
  • Separate algorithm implementation evidence from FIPS 140-3 cryptographic module validation evidence.
  • Record CAVP or CMVP certificate references only when they match the implementation, operational environment, and module boundary being claimed.
  • Track post-quantum migration questions without implying that every legacy RSA, ECDSA, or ECDH use case has the same replacement path.
