About SSL Certificate Checking

This tool queries Certificate Transparency logs via crt.sh to find SSL/TLS certificates issued for a domain. It also tests whether the domain is reachable over HTTPS.

  • Certificate Transparency is a public framework for monitoring and auditing SSL certificates
  • Expired certificates are flagged in red
  • Results show the 20 most recent unique certificates
