What is the Certificate Chain?

The list of SSL certificates, from the root certificate to the end-user certificate, represents a SSL certificate chain, or intermediate certificate. These must be installed to a web server along with a primary certificate. If they aren't installed web browsers will display an "Invalid certificate" or "certificate not trusted" error. You can use our SSL Certificate Check tool to validate your chain.
