MyInfo v4 cert and JWKS

This is the code

const jose = require('node-jose');
const crypto = require('crypto');
async function generateKey(){
  let key = crypto.generateKeyPairSync('ec', {
    namedCurve: 'prime256v1',
    publicKeyEncoding: {
      type: 'spki',
      format: 'pem',
    },
    privateKeyEncoding: {
      type: 'pkcs8',
      format: 'pem',
    },
  });
  let cryptoKey = await jose.JWK.asKey(key.privateKey, 'pem');
  console.log(cryptoKey.toPEM(true));
  return cryptoKey;
}
async function generateJwks() {
  //Creating Signing Key
  let signingKey = await generateKey();
  let publicSigningKeyJSON = signingKey.toJSON();

  //Creating Encryption Key
  let encryptionKey = await generateKey();
  let publicEncryptionKeyJSON = encryptionKey.toJSON();

    let jwks = {
      keys: [{...publicSigningKeyJSON,
              ...{use: 'sig'},
              ...{crv: 'P-256'},
              ...{alg: 'ES256'},
    },
    {...publicEncryptionKeyJSON,
              ...{use: 'enc'},
              ...{crv: 'P-256'},
              ...{alg: 'ECDH-ES+A256KW'},
    }]};

    console.log(JSON.stringify(jwks));
}
generateJwks();

and this is the sample output

Then you can start using them with MyInfoConnector for NodeJS lib with their sample app. Happy Coding!
