FIPS 186-5 Digital Signature Standard (DSS) ECDSA Auditor
Audits Elliptic Curve Digital Signature Standard (ECDSA) curve selections (P-256, P-384, P-521) against FIPS 186-5.
Notice: engineering verification utility. Use test or de-identified data and verify results independently before relying on them.
How it works
Standard: NIST FIPS 186-5 Digital Signature Standard (DSS)
Formula: Verify curve name (secp256r1, secp384r1, secp521r1) and signature byte verification
Checks: Valid curve parameter and signature string
