About the SSL Certificate Checker
Inspect a domain's live TLS certificate: issuer, subject, validity dates and days remaining, via a direct TLS connection from our server.
The SSL Certificate Checker is part of the Network Tools collection on Tool Magic Lab. DNS lookups, SSL certificate checks, RDAP domain data, status, speed and security-header checks — run server-side with SSRF protection.
This tool fetches the live URL you enter from our server, with SSRF protection, rate limits and timeouts, and reports exactly what it found — including when a site blocks automated checks.
