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. [Jump to guides](#topics) ## 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. Grounded in NIST primary sources | Current PQC FIPS releases | No signup required ### 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. | Value | Metric | | --- | --- | | 5 | Guides | | 2023-05-09 | AES upd1 | | 2023-02-03 | DSS | | 2024-08-13 | PQC FIPS | **Key highlights:** Inventory | Safe defaults | Evidence ## Topic Guides - [AES (FIPS 197) - How to Use AES Safely](/artifacts/global/fips-crypto-algorithms/aes-fips-197.md): Advanced implementation guide for AES under FIPS 197 upd1: AES-128, AES-192, AES-256, approved modes. - [Digital Signatures (FIPS 186-5 DSS and FIPS 204 ML-DSA)](/artifacts/global/fips-crypto-algorithms/digital-signatures-fips-186-5-and-fips-204.md): Advanced guide to FIPS digital signatures: RSA, ECDSA, deterministic ECDSA, EdDSA, and post-quantum ML-DSA. - [FIPS Crypto Algorithms FAQ (AES, SHA, Signatures, PQC)](/artifacts/global/fips-crypto-algorithms/faq.md): FAQ for FIPS crypto adoption: AES, SHA-2 and SHA-3, digital signatures, post-quantum standards. - [Post-Quantum Cryptography (FIPS 203, 204, 205) - Migration Guide](/artifacts/global/fips-crypto-algorithms/post-quantum-fips-203-204-205.md): Practical post-quantum cryptography migration guidance grounded in FIPS 203, FIPS 204, and FIPS 205. - [Secure Hash (FIPS 180-4 SHA-2, FIPS 202 SHA-3, SHAKE)](/artifacts/global/fips-crypto-algorithms/secure-hash-fips-180-4-and-fips-202.md): Deep guide to FIPS secure hash standards: SHA-2 under FIPS 180-4 and SHA-3 plus SHAKE under FIPS 202.
