What is SSL Certificate Checker?
An SSL/TLS certificate encrypts the connection between a visitor's browser and a website's server. Our SSL checker connects directly to the server on port 443, retrieves the certificate chain, and parses it to show the issuer, validity dates, subject, and Subject Alternative Names (SANs). This helps you verify that a site's certificate is valid, not expired, and issued by a trusted Certificate Authority.
