Check HTTPS certificate status for the active tab. SSL Checker helps you quickly analyze SSL certificate and domain registration details for the website you are currently viewing. With a single click, you can check whether a website's SSL certificate is valid, when it expires, who issued it, which domains are covered, and what TLS settings are being used. The extension also includes Whois/RDAP registration details, helping website owners, developers, SEO specialists, IT administrators, and security professionals review important domain and HTTPS information without leaving the browser. How It Works: - Open any website in Chrome - Click the SSL Checker extension icon - View SSL certificate, TLS, SAN, and Whois details instantly What SSL Checker Shows: - SSL certificate validity - Expiration date and days remaining - Certificate issuer and subject - Serial number - SHA-256 fingerprint - Public key type and key size - TLS protocol and cipher - Subject Alternative Names (SANs) - Whois/RDAP domain registration details - Registrar information - Domain creation, update, and expiration dates - Name servers and domain status Why Use SSL Checker: - Quickly identify expired or invalid certificates - Review HTTPS certificate details in one click - Check whether the current hostname is covered by the certificate - Monitor certificate expiration before it affects visitors - View domain registration information alongside SSL details - Useful for website audits, development, SEO checks, and security reviews Privacy: SSL Checker only checks the hostname of the active tab when you open the extension. It does not read page content, cookies, form data, passwords, browsing history, or local storage. The active hostname is sent to RightSSL.com to retrieve SSL certificate and Whois/RDAP information.
