Why Should I Check SSL Certificate?

The check of the SSL certificate is required to check out whether the display of the certificate’s parameters is right. Though even the best web hosts don’t provide this information. Such tests usually check out server’s parameters, certificate’s validity period, SAN, and chains of trust.

The following tools show errors (if they exist) and help to adjust the work of the certificate to your website.
