>_ SSL Certificate Checker

Check if a website has a valid SSL/TLS certificate. Tests HTTPS connectivity and reports certificate status.

Note: Browser-based SSL checking is limited. We test HTTPS connectivity. Detailed cert inspection (issuer, expiry, chain) requires a server-side API.

What We Check

  • HTTPS connectivity (port 443)
  • Whether the site redirects HTTP to HTTPS
  • Response status code
  • Security headers (HSTS, X-Frame-Options, etc.)

FAQ

Why can't you show certificate details?>
Browsers don't expose SSL certificate details to JavaScript for security reasons. We can only test HTTPS connectivity and check response headers. For full cert inspection, use openssl CLI or a server-side tool.
