FIPS Crypto Algorithms Implementation Hub

Use this hub to understand what each FIPS crypto standard actually specifies and how to implement it in real systems. The focus is practical engineering and assurance: algorithm selection, safe defaults, interoperability, and evidence that can support FIPS 140-3 approved-mode claims.

Grounded in FIPS 197 upd1, FIPS 180-4, FIPS 202, FIPS 186-5, and the August 13, 2024 PQC FIPS releases: FIPS 203, FIPS 204, and FIPS 205.

What you can do here
Choose the right algorithm family
Pick AES, SHA-2, SHA-3, classic signatures, or PQC based on protocol and assurance requirements.
Implement with safe constraints
Avoid common failures such as weak mode choices, digest drift, key-purpose reuse, and uncontrolled PQC negotiation.
Prepare evidence that survives review
Build inventories, configuration manifests, test artifacts, and source links that support security reviews and module validation.

Coverage
FIPS
AES
FIPS 197 defines AES-128, AES-192, and AES-256 and requires use with a FIPS-approved or NIST-recommended mode of operation.
Secure hash
FIPS 180-4 and FIPS 202 together cover SHA-2, SHA-3, and approved XOFs such as SHAKE128 and SHAKE256.
Signatures and PQC
FIPS 186-5 covers RSA, ECDSA, deterministic ECDSA, and EdDSA. FIPS 203, 204, and 205 add ML-KEM, ML-DSA, and SLH-DSA.
FIPS algorithm work is easiest when you treat it as a system: inventory, selection, implementation, verification, and controlled evidence.
