Encrypted Data used for Authentication is contained in the Root of a Certificate

The roof of a certificate contains encrypted data used for authentication purposes. This data is loaded into the digital certificate when it is created by your certificate authority (CA) system. The root also contains details about the location of the CA system it will connect with to perform authentication and verify the certificate can be trusted. Trust is established between the digital certificate and CA system whenever the authentication procedures stored in the root run.

A Root Certificate is found in All Types of Digital Certificates

All types of digital certificates will contain a specific location for the root certificate. The root is a necessary component in order for digital certificates to perform correctly. Without this root, your digital certificates may still allow for some functionality, however, the certificates would not be able to be authenticated against a CA system. Further, a certificate missing its root cannot be trusted.
