What does this tool check?

  • Certificate subject — the domain or hostname the certificate was issued for.
  • Issuer & CA chain — whether the certificate is signed by a trusted Certificate Authority.
  • Expiry date — days remaining before the certificate expires.
  • Self-signed flag — whether the certificate is self-signed (common in private FTP setups).
  • TLS version negotiated — which TLS version was used during the handshake.
