Background

Provides interoperability tests for verifiable credential processors (issuers and verifiers) that support ECDSA Data Integrity cryptosuites.

Implementation

You will need an issuer and verifier that are compatible with VC API and are capable of handling issuance and verification of Verifiable Credentials with DataIntegrityProof proof type using the ecdsa-rdfc-2019, ecdsa-jcs-2019, or ecdsa-sd-2023 cryptosuites.

To add your implementation to this test suite, you will need to add 2 endpoints to your implementation manifest.

A credential issuer endpoint (/credentials/issue) in the issuers property.
- An optional id property may be set alongside the endpoint.
- If provided, the specified issuer.id will be added to Verifiable Credentials in the tests.
- If present, the issuer.id MUST use the did:key method.
- If the endpoint supports a selective disclosure suite
- The endpoint must accept options.mandatoryPointers.
- If present, options.mandatoryPointers is an array of strings.
A credential verifier endpoint (/credentials/verify) in the verifiers property.
An optional vcHolder endpoint can be added for ecdsa-sd-2023 selective disclosure tests.
- The vcHolder endpoint route is meant to be /credentials/derive
- The endpoint is expected to accept a JSON object with 2 properties:
- options which is a JSON object.
- options.selectivePointers which is an array of strings.
- verifiableCredential which is a previously signed JSON verifiable credential.
- The endpoint needs to use ecdsa-sd-2023 for the derived verifiable credential.

All endpoints will require a cryptosuite tag of ecdsa-rdfc-2019, ecdsa-jcs-2019, and/or ecdsa-sd-2023. Alongside this cryptosuite tag, you will need to specify the supportedEcdsaKeyTypes property, parallel to tags listing the ECDSA key types issuable or verifiable by your implementation. It is recommended to have one issuer per supported ECDSA key type. Issuers and Verifiers may support more than one VC version. Use the property supports.vc with the values "1.1" and/or "2.0" to signal support for versions of Verifiable Credentials on your endpoints. Currently, the ecdsa-rdfc-2019 test suite supports P-256 and P-384 ECDSA key types. The ecdsa-sd-2023 test suite only supports the P-256 ECDSA key type. Verifier endpoints can support multiple keys, key types, and suites. A vcHolder tag is required for the vcHolder endpoints.

NOTE: The tests for ecdsa-jcs-2019 are TBA.

A simplified manifest would look like this:

{
  "name": "My Company",
  "implementation": "My implementation",
  "issuers": [{
    "id": "did:key:myIssuer1#p256",
    "endpoint": "https://mycompany.example/issuer/p256/credentials/issue",
    "method": "POST",
    "supportedEcdsaKeyTypes": ["P-256"],
    "supports": {
      "vc": ["1.1", "2.0"]
    },
    "tags": ["ecdsa-rdfc-2019"]
  },{
    "id": "did:key:myIssuer1#p384",
    "endpoint": "https://mycompany.example/issuer/p384/credentials/issue",
    "method": "POST",
    "supportedEcdsaKeyTypes": ["P-384"],
    "supports": {
      "vc": ["1.1", "2.0"]
    },
    "tags": ["ecdsa-rdfc-2019"]
  }, {
    "id": "did:key:myIssuer#issuer2",
    "endpoint": "https://mycompany.example/credentials/issue",
    "method": "POST",
    "supportedEcdsaKeyTypes": ["P-256"],
    "supports": {
      "vc": ["1.1", "2.0"]
    },
    "tags": ["ecdsa-jcs-2019"]
  }, {
    "id": "did:key:myIssuer3",
    "endpoint": "https://mycompany.example/credentials/issue",
    "method": "POST",
    "supportedEcdsaKeyTypes": ["P-256"],
    "supports": {
      "vc": ["1.1", "2.0"]
    },
    "tags": ["ecdsa-sd-2023"]
  }],
  "verifiers": [{
    "endpoint": "https://mycompany.example/credentials/verify",
    "method": "POST",
    "supportedEcdsaKeyTypes": ["P-256", "P-384"],
    "supports": {
      "vc": ["1.1", "2.0"]
    },
    "tags": ["ecdsa-rdfc-2019", "ecdsa-jcs-2019", "ecdsa-sd-2023"]
  }],
  "vcHolders": [{
    "id": "did:key:myIssuer1#keyFragment",
    "endpoint": "https://mycompany.example/credentials/derive",
    "tags": ["vcHolder"]
  }]
}

The example above represents an unauthenticated endpoint. You may add ZCAP or OAuth2 authentication to your endpoints. You can find an example in the vc-test-suite-implementations README.

To run the tests, some implementations may require client secrets that can be passed as environment variables to the test script. To see which implementations require client secrets, please check the implementation manifest within the vc-test-suite-implementations library.

Usage

npm i

Testing Locally

To test a single implementation or endpoint running locally, you can copy localConfig.example.cjs to localConfig.cjs in the root directory of the test suite.

cp localConfig.example.cjs localConfig.cjs

This file must be a CommonJS module that exports an object containing a settings object (for configuring the test suite code itself) and an implementations array (for configuring the implementation(s) to test against).

The format of the object contained in the implementations array is identical to the one defined in VC Test Suite Implementations). The implementations array may contain more than one implementation object, to test multiple implementations in one run.

// localConfig.cjs defines local implementations
// you can specify a BASE_URL when running the tests such as:
// BASE_URL=http://localhost:40443/zDdfsdfs npm test
const baseUrl = process.env.BASE_URL || 'https://localhost:40443/id';
module.exports = {
  settings: {
    enableInteropTests: false, // default
    testAllImplementations: false // default
  },
  implementations: [{
    name: 'My Company',
    implementation: 'My Implementation Name',
    // only this implementation will be run in the suite
    issuers: [{
      id: 'did:key:zMyKey',
      endpoint: `${baseUrl}/credentials/issue`,
      supportedEcdsaKeyTypes: ['P-256'],
      tags: ['ecdsa-rdfc-2019']
    }],
    verifiers: [{
      endpoint: `${baseUrl}/credentials/verify`,
      supportedEcdsaKeyTypes: ['P-256'],
      tags: ['ecdsa-rdfc-2019']
    }]
  }];

Running Interoperability Tests

Running interoperability tests requires having authorization to the endpoints of multiple implementations. Because most users of this suite will not have those authorization capabilities, the interoperability suites are disabled by default. You can try running the interoperability suites by adding enableInteropTests: true to your localConfig.cjs file.

Development

Configuring the Tests

The suites call on a set of common config files stored at ./config/.

./config/runner.json is for test suite specific configurations.
./config/vector.json is for test vector specific configurations.

These test suites use tags matched to implementation endpoint tags in the tests. You can change the tag on which the suites will run in ./config/runner.json, if desired.

For this suite, the runner.json file looks like this:

{
  "suites": {
    "ecdsa-rdfc-2019": {
      "tags": ["ecdsa-rdfc-2019"]
    },
    "ecdsa-sd-2023": {
      "tags": ["ecdsa-sd-2023"],
      "vcHolder": {
        "holderName": "Digital Bazaar",
        "tags": ["vcHolder"]
      }
    }
  }
}

Configuring Test Vectors

The tests use a configuration file /config/vectors.json to configure test vectors. Test Vector configuration is documented in testVectorGuide.md,
