Check the validity of the SSL certificate for website

The SSL certificate checking process takes place in the following stages:

  1. A request to review the SSL certificate is sent via the online form on this webpage for a specific domain. In this case
  2. Our Server first resolves the domain into an IP address ( in this case a domain name resolve to an IP address and then connects to the server of the given website asking for a digital identification (SSL certificate)
  3. The server of the requested domain sends us a response in the form of a copy of the SSL certificate (if they have one)
  4. Our tool checks to see if it is a valid SSL certificate or not and shows you the result of the checking process

The entire testing process is very fast and takes place in milliseconds.

If you are the owner of the domain and if the SSL test shows that the website does not use a valid SSL certificate, then consider buying a valid SSL certificate as soon as possible and ensure the safety and trust of your visitors in your website and your online business.

A complete overview with all visible details, after checking the SSL certificate for the requested domain, with the final conclusion, can be seen below.
