The CA Hierarchy provides a structured representation of Certificates, including Root, CA, and Sub CA certificates, in a hierarchical format. This presentation outlines the certificate chain and enables users to access and export certificate details by selecting a specific certificate. Additionally, the hierarchical view indicates the availability of the private key for a given CA Certificate.
