At the heart of all types of digital certificates is a root certificate. The root certificate contains specific types of information which is needed during authentication processes. The root contains the values and locations of where to look to find the matching private key, when it is held within a certificate containing a public key. Once it connects to the location, the root then calls for the authentication processes to run. As long as they are successful the user is able to gain access.
