Health & Security Audit

100/100
Modern Elliptic Curve (secp256r1 (NIST P-256))

Provides superior performance, compact signatures, and high cryptographic security.

Fix: Excellent configuration.

Lifespan (91 Days) Exceeds Upcoming 90-Day Policy

Google Chromium Root Program proposed reducing maximum validity from 398 days to 90 days.

Fix: Prepare automated rotation pipelines to support 90-day validity cycles.
