About
ssl-inspect opens a real TLS handshake to the target host and returns everything the certificate dump tells you, in structured form:
• **Chain** — every cert in the presented chain (leaf → intermediates → root if sent), parsed: subject, issuer, serial, validity window, signature algorithm, fingerprint, SANs. • **Cipher** — negotiated cipher suite (name, standardName, TLS version). • **Authorization** — Node's verify-by-default outcome plus the raw `authorizationError` if any. Toggle `rejectUnauthorized: false` to inspect self-signed or expired certs without tearing down. • **Summary** — daysUntilExpiry, isExpired, isExpiringSoon (<30d), matchesHost (SAN/CN check), hasWeakSignature (SHA-1 / MD5 flag).
Use it for: cert-expiry monitoring (cron + Slack alert), pre-deployment checks, hardening audits, debugging CDN cert misconfiguration. 10-second connect timeout.
