      <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."/>
