SSL Lookup

0 out of 0 stars

The SSL Lookup tool connects to a server and fetches the SSL/TLS certificate details. You can verify the certificate’s issuer, check its validity period, and see which hostnames it covers (common name and Subject Alternative Names). This is useful for diagnosing certificate errors, ensuring your certificate is correctly installed, and monitoring expiration dates to avoid unexpected downtime. The tool also shows the signature algorithm and can help identify weak or outdated cryptographic settings.
