Tools for testing your site’s certificate

We recommend two tools for testing SSL certificates.

1. SSL Shopper Checker – https://www.sslshopper.com/ssl-checker.html

This is a simple tool and it will list only some values like IP of the site, server type, certificate issuer, certificate expiration etc. If everything is ok with your certificate you will see only green checkmarks and padlocks.
