SSL Certificate Checker connects to domains over TLS and inspects their SSL certificates. It returns structured data about certificate validity, expiry, issuer chain, TLS protocol version, cipher suite, and a security grade from A+ to F.

Check SSL/TLS certificates for any website: expiration date, issuer, subject, hostname match (SNI), chain/authorization status, and common HTTPS misconfigurations. Useful for SEO audits, security checks, and uptime monitoring.
