📝 WalkthroughWalkthroughThe change adds SEC1 PEM support for private-key matching, rejects unparseable nonempty private keys as mismatched, and adds P-384 ECDSA-SHA256 certificate-link coverage. Existing validation behavior is reformatted without semantic changes. ChangesKey validation updates
Priority: ➖ Normal Estimated code review effort: 2 (Simple) | ~12 minutes Change: Bug fix · Severity of issue fixed: Medium Merge Risk: 🔵 Low · up to SEC1 support may regress without CI detecting it for P-256 or P-384 keyboxes. Add the assertions before merging to preserve the intended validation support. 🚥 Pre-merge checks | ✅ 3 | ❌ 2❌ Failed checks (2 warnings)

Full details: Linked Issues checkExplanation The changes address the linked keybox failures by adding P-384 ECDSA-SHA256 verification and SEC1 EC-key handling. The implementation does not meet the required failure behavior from [ Resolution Return

435-445: 🎯 Functional Correctness | 🔵 Trivial | ⚡ Quick winAdd a P-384 ECDSA-SHA256 certificate-link regression test. The existing
ecdsa_p256_self_signed_link_verifiestest covers only the P-256 branch. No test or fixture reachesverify_signaturewhenOID_ECDSA_SHA256is paired withOID_CURVE_P384. A regression in P-384 public-key parsing, SHA-256 prehashing, or DER-signature verification can therefore pass the current test suite. Add a valid P-384 certificate-link fixture and assert successful validation. Add an invalid-signature case to ensure the link is rejected.🤖 Prompt for AI Agents
