What is an SSL Checker?
An SSL Checker is an online tool that verifies the status and validity of a website’s SSL certificate. SSL (Secure Sockets Layer) certificates encrypt data transferred between a browser and a server, ensuring secure communication. This free SSL Checker instantly analyzes certificate details including expiry date, issuer, encryption strength, and potential configuration issues — no installation or registration needed.
How SSL Checking Works
The SSL Checker connects to the website’s server and retrieves its SSL certificate. It evaluates core information such as the certificate’s validity, expiration date, domain match, and chain of trust. The tool highlights any weaknesses or misconfigurations that could affect site security or browser trust warnings.
