unicalwallet-cli

Symbol CLI wallet

A Command Line Interface with mnemonic private key generator for the Symbol Blockchain provided by NEM.

This project is connected with the course provided on Blockchain Course

You will find a step by step video course in how to build it on that course link

If you want to test the app and receive some UnicalCoins just send me an email with your ADDRESS ;)

Mnemonic Private Key Generator

The following code show the builded function used to create a mnemonic private key starting from 4 random english words, hashing them like a mini markle tree and giving back a private key of 64 bit (sha256).

var mnGen = require('mngen');
import hasha from 'hasha';
var colors = require('colors/safe');

function sha256(word: string): string {
  return hasha(word, { algorithm: 'sha256', encoding: 'hex' });
}

export function generateMnemonicPrivateKey(): string {
  const mnemonic: string[] = mnGen.list(4); // [provide,crimson,float,carrot]

  console.log(
    `Write down those mnemonic worlds that are used to generate your private key:`
  );
  console.log(colors.yellow(`\n${mnemonic}`));

  let hashes: string[] = [];
  mnemonic.map((world) => {
    hashes.push(sha256(world));
  });

  // Pseudo Merkle Tree
  let tmp_result_1 = sha256(hashes[0] + hashes[1]);
  let tmp_result_2 = sha256(hashes[2] + hashes[3]);

  let privateKey = sha256(tmp_result_1 + tmp_result_2);

  return privateKey;
}
