Installation

• Node.js 16.0+ is required.

To install locally (for development):

git clone  https://github.com/RadicalLedger/zedeid-did-method-ethr.git
cd zedeid-did-method-ethr

yarn install or npm install
yarn test or npm run test

Usage

Initializing and Generating Keys

Generate ethr method key pairs with getKeys method. It can be used to generate key pairs for given node (bip32).

import { BIP32Factory } from 'bip32';
import * as ecc from 'tiny-secp256k1';
import EthrMethod from 'zedeid-did-method-ethr';

const seed = 'your-seed';

const bip32 = BIP32Factory(ecc);
const masterNode = bip32.fromSeed(Buffer.from(seed, 'hex'));

const ethrMethod = new EthrMethod();
const keys = await ethrMethod.getKeys(masterNode);

console.log(keys);

Generating DID Documents

Generate did document with getDocument method.

const privateKey = 'your-private-key-as-hex-string';
const didDocument = await ethrMethod.getDocument(privateKey);

console.log(didDocument);

Generate Verification Key

Generate verification key with createVerificationMethod method for a given seed.

const seed = 'your-seed-as-hex-string';
const includePrivateKey = true; // (optional) to include the private key in the verification method
const verificationKey = await ethrMethod.createVerificationMethod(seed, includePrivateKey);

console.log(verificationKey);
