CLI Tool for splitting a validator key into a predefined threshold of shares via Shamir-Secret-Sharing (SSS), and encrypt them with a set of operator keys.

const keystore = require('./test.keystore.json');
const operatorKeys = require('./operators.json');
const operatorIds = require('./operatorIds.json');
const keystorePassword = 'testtest';

const TEST_OWNER_NONCE = 1;
// The cluster owner address
const TEST_OWNER_ADDRESS = '0x81592c3de184a3e2c0dcb5a261bc107bfa91f494';

async function main() {
  // Step 1: read keystore file
  const ssvKeys = new SSVKeys();

  const operators = operatorKeys.map((operatorKey, index) => ({
    id: operatorIds[index],

  }));

  // Step 2: Build shares from operator IDs and public keys
