QR Link / Encryption

info

Please note that this content is under development and is not ready for implementation. This status message will be updated as content development progresses.

The QR Link / Encryption feature is a crucial component of the UNTP ecosystem, providing a standardised way to access, verify, and render credentials.

For detailed information about the Verify Link structure and usage, please refer to the Verify Link documentation.

Testing Instructions​

To test your QR Link / Encryption implementation, follow these steps:

  1. Obtain a Verify Link: Obtain a verify link produced by your implementation that you would like to test.

  2. Update the Configuration:

    • Navigate to the config file: packages/vc-test-suite/config.ts

    • Update the QrLinkEncrypted section with your verify link (see payload structure). The file should look similar to this:

      export default {
        implementationName: 'UNTP ACME',
        testSuites: {
          QrLinkEncrypted: {
            url: 'https://example.com/credential-verifier?q=%7B%22payload%22%3A%7B%22uri%22%3A%22https%3A%2F%2Fapi.vckit.showthething.com%2Fencrypted-storage%2Fencrypted-data%2F0a6031a9-2740-49cd-b12b-1ed02820f01d%22%2C%22key%22%3A%22d0ad322ec820a0a420262a6b7dbdafb16eb1d35af459182022bc531d18643546%22%2C%20%22hash%22%3A%20%22QmX8fk9hygXQDbt4KsGEMiUXbt7HDRnb772HNcKtZcL2Zr%22%7D%7D',
            headers: {},
            method: 'GET',
          },
        },
      };

    Replace the url value with your verify link.

  3. Run the Test:

    • Navigate to packages/vc-test-suite
    • In your terminal, run the command: yarn test

  4. View Test Results:

    • Navigate to packages/vc-test-suite/reports/index.html
    • Open this file in a web browser
    • Look for the "QR Link Verification" section to view your test results

These tests will validate that your QR Link / Encryption implementation adheres to the UNTP protocol.

Payload Structure​

The QR Link payload is a crucial part of the verification process. Let's break down the structure of the payload:

QrLinkEncrypted: {
  url: 'https://example.com/credential-verifier?q=%7B%22payload%22%3A%7B%22uri%22%3A%22https%3A%2F%2Fapi.vckit.showthething.com%2Fencrypted-storage%2Fencrypted-data%2F0a6031a9-2740-49cd-b12b-1ed02820f01d%22%2C%22key%22%3A%22d0ad322ec820a0a420262a6b7dbdafb16eb1d35af459182022bc531d18643546%22%2C%20%22hash%22%3A%20%22QmX8fk9hygXQDbt4KsGEMiUXbt7HDRnb772HNcKtZcL2Zr%22%7D%7D',
  headers: {},
  method: 'GET',
},

  • url: This is the full URL for the credential verifier, including the encoded payload.

  • headers: An object containing any additional HTTP headers required for the request to the storage service. In this example, it's empty, but you may need to add headers depending on your implementation.

  • method: The HTTP method used to request the verifiable credential from the storage service. In this case, it's set to 'GET'.

The uri within the payload points to the storage service that will return the verifiable credential. The headers and method are used in the request to this storage service.
