Domain Certificates are documents which hold the routing, cryptography, and additional details for the hostname. The routing information is the destination’s IP address. The cryptography is the Master and Ephemeral keypairs to validate and initiate a bi-directional UDSP connection to the origin server. Additional details such as the hostnames which are assigned to the document, cross-origin policy, 0-RTT support, Geo-location based IP, and others are available.
