Verifiable Credentials Step By Step

How identity is managed with Umqhele.

Firstly generate a ed25519 key-pair which can be found at Transmute DID Key:

import * as ed25519 from '@transmute/did-key-ed25519';
import crypto from 'crypto';

const seed = crypto.randomBytes(32).toString('hex');
let key = await Ed25519KeyPair.generate({
  secureRandom: () => {
    return Buffer.from(seed, 'hex');
  },
});

Then you generate a DID document using the key-pair generated above. In order to generate the document, you first have to install npm i @transmute/did-key-common@latest --save and then pass the key generated above to the keyToDidDoc function.

import crypto from 'crypto';
import * as ed25519 from '@transmute/did-key-ed25519';
import { keyToDidDoc } from '@transmute/did-key-common';

const seed = crypto.randomBytes(32).toString('hex');
let ed25519Key = await Ed25519KeyPair.generate({
  secureRandom: () => {
    return Buffer.from(seed, 'hex');
  },
});
const diddoc = await keyToDidDoc(ed25519Key);
