SSL/TLS Certificate Checker

Deep scan your domain's security certificate. Verify chain, expiry, and encryption strength instantly.

Why SSL/TLS Matters

SSL (Secure Sockets Layer) and its successor TLS (Transport Layer Security) are standard protocols used to establish an encrypted link between a web server and a browser. This ensures that all data passed between the web server and browsers remain private and integral.

Authentication

Verifies that the server is who it claims to be.

Encryption

Protects data from being read by third parties.

Integrity

Ensures data has not been altered in transit.

Standard & Disclaimer

This tool performs a passive scan of the SSL/TLS configuration presented by the server. It checks for validity dates, issuer trust, and supported ciphers during the handshake.It does not perform a full penetration test or check for all possible vulnerabilities (like Heartbleed or POODLE) exhaustively. For a complete security audit, consult a professional security engineer.
