About SSL/TLS Certificates

SSL/TLS certificates establish encrypted connections between web servers and browsers. This tool helps you verify certificate validity, check expiration dates, identify the issuing authority, and detect potential security misconfigurations like weak key sizes or domain mismatches.

Note: This tool connects to the specified domain to retrieve its public SSL/TLS certificate information.
