Usage

Initializing and Generating Keys

Generate moon 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 MoonMethod from 'zedeid-did-method-moon';

const seed = 'your-seed';

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

const moonMethod = new MoonMethod();
const keys = await moonMethod.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 moonMethod.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 moonMethod.createVerificationMethod(seed, includePrivateKey);

console.log(verificationKey);
