1.1. Uses for Certificates
The purpose of certificates is to establish trust. Their usage varies depending on the kind of trust they are used to ensure. Some kinds of certificates are used to verify the identity of the presenter; others are used to verify that an object or item has not been tampered with.
For information on how certificates are used, the types of certificates, or how certificates establish identities and relationships, see the Certificates and Authentication
