Implementation Compliance Checklist

Use this checklist to ensure your SHA-224 implementation meets all regulatory requirements:

Algorithm Implementation

Using NIST-specified H(0) values: c1059ed8, 367cd507, 3070dd17, f70e5939, ffc00b31, 68581511, 64f98fa7, befa4fa4

Message padding follows Merkle-Damgård construction with bit '1', zeros, and 64-bit length

Implementation passes all NIST CAVP test vectors

Security Controls

Sensitive data cleared from memory after use (zeroing/overwriting)

Constant-time operations implemented where applicable

Proper validation of input data size and format

Operational Requirements

Cryptographic operations logged for compliance audit trail

Secure error handling without information disclosure

Implementation version tracking and update procedures

Documentation Requirements

Documented cryptographic security policy and procedures

Complete implementation documentation for developers

Procedures for cryptographic compromise or vulnerabilities

Important Compliance Considerations

FIPS Mode Requirement

When operating in FIPS mode, ensure that only FIPS-approved algorithms are used throughout the entire cryptographic boundary. SHA-224 must not be mixed with non-approved algorithms.

Key Derivation Usage

While SHA-224 can be used in HMAC constructions for key derivation, NIST SP 800-108 recommends using approved KDF mechanisms. Ensure your usage aligns with current NIST recommendations.

Migration Timeline

Although SHA-224 remains approved, consider NIST's post-quantum cryptography timeline. Plan for eventual migration to quantum-resistant algorithms by 2030.
