Generating Signed DVR Token

This flow diagram illustrates the process of Generating Signed DVR Token

Step 1: Import Addition Required Modules

Import the addition necessary modules at the beginning of your Code:

import type { DataVerificationRequest } from "@didpass/verifier-sdk";

Step 2: Initialize DataVerificationRequest Instance

Initialize the DataVerificationRequest instance to be signed:

const user_data_verifying_key = {
    KeysetEndpoint: {
        jku: "YOUR_ISSUER_JWK_SET_URL",
        kid: "YOUR_ISSUER_KID",
    },
};
const dvr = new DataVerificationRequest(
    dvrTitle, //YOUR_DVR_TITLE
    dvrId, //YOUR_DVR_ID
    query_engine_ver, //YOUR_QUERY_ENGINE_VERSION, you get this from zkpass-client
    query_method_ver, //YOUR_QUERY_METHOD_VERSION, you get this from zkpass-client
    query, //YOUR_FULL_QUERY
    user_data_url, //YOUR_USER_DATA_URL
    user_data_verifying_key
);

Step 3: Set Up Details

Replace the placeholder values with your actual details:

const dvrDto = {
    keyInPem: "YOUR_VERIFIER_PRIVATE_KEY",
    dvr, //Initialized in Step 2
    verifyingKeyJKWS: {
        jku: "YOUR_VERIFIER_JWK_SET_URL",
        kid: "YOUR_VERIFIER_KID",
    },
};

const siweDto = {
    siweMessage: "YOUR_SIWE_MESSAGE",
    siweSignature: "YOUR_SIWE_SIGNATURE"
}

Step 4: Generate Signed DVR

Generate the signed DVR token:

const signedDVRToken = await verifier.signDvrToken(
    dvrDto,
    siweDto
);

Step 5: Return Signed DVR Token

Return the generated signed DVR Token:

return signedDVRToken;

Final Code

Here's the complete code:

import type { Verifier, DataVerificationRequest } from "@didpass/verifier-sdk";

async function generateSignedDvrToken() {
  const verifier = new Verifier();
  const user_data_verifying_key = {
    KeysetEndpoint: {
      jku: "YOUR_ISSUER_JWK_SET_URL",
      kid: "YOUR_ISSUER_KID",
    },
  };
  const dvr = new DataVerificationRequest(
    dvrTitle, //YOUR_DVR_TITLE
    dvrId, //YOUR_DVR_ID
    query_engine_ver, //YOUR_QUERY_ENGINE_VERSION, you get this from zkpass-client
    query_method_ver, //YOUR_QUERY_METHOD_VERSION, you get this from zkpass-client
    query, //YOUR_FULL_QUERY
    user_data_url, //YOUR_USER_DATA_URL
    user_data_verifying_key
  );
  const dvrDto = {
    keyInPem: "YOUR_VERIFIER_PRIVATE_KEY",
    dvr, //Initialized in Step 2
    verifyingKeyJKWS: {
      jku: "YOUR_VERIFIER_JWK_SET_URL",
      kid: "YOUR_VERIFIER_KID",
    },
  };

  const siweDto = {
    siweMessage: "YOUR_SIWE_MESSAGE",
    siweSignature: "YOUR_SIWE_SIGNATURE",
  };

  const signedDVRToken = await verifier.signDvrToken(dvrDto, siweDto);
  return signedDVRToken;
}
