01. Examples

• Issuing a SD JWT

import sdjwt, { DisclosureFrame } from '@hopae/sd-jwt';

const { privateKey, publicKey } = createKeyPair();
  const claims = {
    firstname: 'John',
    lastname: 'Doe',
    ssn: '123-45-6789',
    id: '1234',
  };
  const disclosureFrame: DisclosureFrame<typeof claims> = {
    _sd: ['firstname', 'id'],
  };
  const encodedSdjwt = await sdjwt.issue(claims, privateKey, disclosureFrame);
  console.log('encodedSdjwt:', encodedSdjwt);

• Presenting a SD JWT

import sdjwt from '@hopae/sd-jwt';

const presentationFrame = ['firstname', 'id'];
const presentedSDJwt = await sdjwt.present(encodedSdjwt, presentationFrame);
console.log('presentedSDJwt:', presentedSDJwt);

• Verifying a SD JWT

const requiredClaimKeys = ['firstname', 'id'];
const verified = await sdjwt.verify(
  encodedSdjwt,
  publicKey,
  requiredClaimKeys,
);
console.log('verified:', verified);
