Usage

importing DID builder and resolver

ES Modules import

import { JsonWebKey2020 } from '@trustalliance/key'

CommonJS import

const { JsonWebKey2020 } = require('@trustalliance/key');

Example

Generate keypair

const keyPair = await JsonWebKey2020.generate();

// {
//   id: 'did:trustalliance:key:...-pXbFqo#...-pXbFqo',
//   type: 'JsonWebKey2020',
//   controller: 'did:trustalliance:key:...-pXbFqo',
//   publicKeyJwk: {
//     crv: 'Ed25519',
//     x: 'THLsqR-...-3FDg',
//     kty: 'OKP',
//     alg: 'EdDSA',
//   },
//   privateKeyJwk: {
//     crv: 'Ed25519',
//     d: '..-URkyPqyYhTc',
//     x: 'THLsqR-...-3FDg',
//     kty: 'OKP',
//     alg: 'EdDSA',
//   },
// }

Sign messages

const signer = keyPair.signer();
const signature = await signer.sign({message:"test"});

Verify signature

const message = {...}

const signer = keyPair.signer();
const signature = await signer.sign(message);

const verifier = keyPair.verifier();
const verified = await verifier.verify({ data: message, signature });

// true / false
