SSL Certificate Checker

Enter a domain name to check its SSL certificate status and configuration.

Why Check Your SSL Certificate?

A properly installed SSL certificate is crucial for modern websites. It enables HTTPS, which encrypts the connection between your website and your visitors, protecting sensitive data like login credentials and payment information. Regular checks are essential to ensure your site remains secure, trusted, and highly ranked on search engines.

Verify Security

Confirm that your certificate is valid, correctly installed, and providing strong encryption for your visitors.

Build User Trust

Avoid browser warnings that scare visitors away. A valid SSL shows customers that your site is authentic and safe for transactions.

Prevent Expiration

Check your certificate's expiry date to ensure you have enough time to renew it, preventing downtime and security lapses.

Improve SEO Ranking

HTTPS is a confirmed Google ranking factor. A valid SSL certificate can directly contribute to better visibility in search results.

How Our SSL Checker Works

Our tool connects to your server to retrieve and analyze the installed SSL certificate. In seconds, you will get a comprehensive report including:

  • Certificate Issuer and Type
  • Validity Period (Issue & Expiry Dates)
  • Days Remaining Until Expiration
  • Certificate Chain and Trust Status

Use this information to diagnose installation issues, plan for renewals, and ensure your website's security is always in top condition.

Frequently Asked Questions

An SSL Checker connects to your web server to inspect the SSL/TLS certificate that is currently installed. It verifies that the certificate is valid, trusted, and correctly configured. Our tool provides a detailed report, including the issuer, validity period, and certificate chain, helping you quickly diagnose any issues.

This error usually occurs if the certificate is self-signed or if the certificate chain is incomplete. A complete chain includes your domain's certificate, any intermediate certificates, and the root certificate from a trusted Certificate Authority (CA). Our checker will help you identify if any part of the chain is missing.

This error means the domain name(s) listed on the SSL certificate do not match the domain you are trying to visit. For example, the certificate might be for "www.example.com" but you are visiting "example.com". Ensure all your domain variations (with and without "www") are included in the certificate's Subject Alternative Names (SANs).

It's a good practice to use an SSL checker after you first install a new certificate to confirm everything is set up correctly. You should also use it if you are experiencing any "not secure" warnings from browsers, or as part of a regular security audit for your website.
