FIPS 197 Advanced Encryption Standard (AES) Key Length Auditor
Audits AES cryptographic key lengths (128, 192, or 256 bits) for FIPS 197 compliance.
Notice: engineering verification utility. Use test or de-identified data and verify results independently before relying on them.
How it works
Standard: NIST FIPS 197 Advanced Encryption Standard (AES)
Formula: Verify key bit length equals 128, 192, or 256
Checks: Valid numeric AES key length in bits
