About SSL/TLS Certificate Checking

SSL/TLS certificates secure communication between web browsers and servers. This tool analyzes certificate validity, expiration dates, security levels, and certificate chain information to help you ensure your domain's security configuration is properly set up.

The checker examines certificate details including issuer information, encryption algorithms, key sizes, and alternative names while also validating the certificate chain and security protocols.
