  <description
               value="A [VHL Sharer](ActorDefinition-VHLSharer.html) or [VHL Receiver](ActorDefinition-VHLReceiver.html), as a participant in the trust network, SHALL be capable of retrieving public key infrastructure (PKI) material from a designated [Trust Anchor](ActorDefinition-TrustAnchor.html).

The retrieved material MAY include:
* Public key certificates and associated trust lists
* Certificate revocation data (e.g., CRLs, OCSP responses)
* Metadata used to:
  - Validate digital signatures on VHLs and related resources
  - Establish secure connections
  - Decrypt content protected via asymmetric encryption

Participants SHOULD cache the received trust list to reduce network and server load.

**Preconditions:**
* The requesting participant knows in advance the endpoint from which to retrieve PKI material, as published or distributed by the Trust Anchor."/>
