@kiltprotocol/jsonld-suites

Data sovereignty and interoperability

Linked Data Proofs Compatibility Package

This package helps integrating KILT credentials with the popular @digitalbazaar/vc library (formerly known as vc-js) for issuing and verifying Verifiable Credentials and related tool chain (jsonld-signatures, crypto-ld & jsonld). It provides you with Linked Data Proof suites and documentLoader implementations that act as plugins to these libraries, enhancing them with support for the proof types and DIDs used in KILT credentials.

Installation

NPM:

npm install @kiltprotocol/jsonld-suites

YARN:

yarn add @kiltprotocol/jsonld-suites

Contents

• KiltAttestationProofV1
  • When used as a suite in @digitalbazaar/vc or jsonld-signatures, you can:
    • verify VCs with a proof type KiltAttestationProofV1.
    • issue a KiltAttestationProofV1 type proof for a KiltCredentialV1 type VC.
    • check the revocation status of a KiltCredentialV1.
• NoProofPurpose
  • ProofPurpose class to be used in combination with the attestation proof suite above.
• Sr25519Signature2020
  • A suite implementation for creating and verifying sr25519 linked data signatures.
• Sr25519VerificationKey2020
  • A key class for use with the above signature suite.
• contexts
  • JSON-LD context defintions for all types and fields used by our suites and credentials.
• defaultDocumentLoader
  • a documentLoader implementation that loads all KILT-specific contexts and credential schemas as well as KILT DID documents and their verification methods.

Examples

See unit test files for usage examples.

• Issuing & verifying a KiltAttestationProofV1 as well as Verifiable Presentations via @digitalbazaar/vc & jsonld-signatures
