SSL Certificate Checker
Check if a website has a valid SSL certificate and test HTTPS connectivity.
About SSL Certificate Checker
This tool checks whether a website has a valid SSL/TLS certificate by attempting an HTTPS connection. It verifies that the site loads over HTTPS and reports the connection status.
What is SSL/TLS?
SSL (Secure Sockets Layer) and TLS (Transport Layer Security) encrypt the connection between your browser and a website. A valid SSL certificate ensures data is transmitted securely and the site's identity is verified.
Limitations
Browser-based tools cannot directly inspect SSL certificate details (issuer, expiry date, key type) due to security restrictions. For full certificate inspection, use command-line tools like openssl s_client.
