To ensure the integrity of external resources linked in Verifiable Credentials, you embed cryptographic digests of those resources directly within the VC. This allows verifiers to confirm that linked content, such as JSON-LD contexts or external documents, has not been tampered with since issuance.

The VCDM resource integrity mechanism supports including cryptographic digests using SHA384 via digestSRI or SHA256 via digestMultibase. These formats allow verifiers to cryptographically verify the authenticity and exact content of related resources referenced within the credential.

You need to add integrity protection to a Verifiable Credential when it links to specific external resources like schema versions or policy documents. Embedding a cryptographic hash of the resource ensures the verifier references the exact same content and detects any tampering.

To securely reference a JSON-LD context in a Verifiable Credential, you include a cryptographic digest of the context resource. This mechanism addresses the need for secure referencing by enabling verifiers to confirm the authenticity and integrity of the linked external data.

Yes, W3C VCDM supports verifying the authenticity of linked external documents by including cryptographic digests for related resources. This enables verifiers to confirm content authenticity and ensures that external data linked within the credential remains untampered.

The best way to protect linked schema content in VCDM from tampering is to embed a cryptographic digest of the schema using digestSRI or digestMultibase. This allows verifiers to confirm they are referencing the exact same content originally intended by the issuer.
