使用Node批量创建ETH钱包

技术/BlockChain

安装Node

Download | Node.js

初始化项目

mkdir ETHWalletGenerator
cd ETHWalletGenerator
npm init

配置ETH相关的环境

npm install secp256k1 
npm install keccak

创建并且编辑ethGenerator.js

'use strict';
console.log('Generator Start..............');
const num = 5;
const secp256k1 = require("secp256k1/elliptic");
const createKeccakHash = require("keccak");
const crypto = require('crypto');
// 地址转换
function toChecksumAddress(address) {
    address = address.toLowerCase().replace('0x', ''); 
    var hash = createKeccakHash('keccak256').update(address).digest('hex'); 
    var ret = '0x'; 
    for (var i = 0; i < address.length; i++) {   
        if (parseInt(hash[i], 16) >= 8) {     
            ret += address[i].toUpperCase();   
        } else {     
            ret += address[i];   
        } 
    } 
    return ret;
}

for (var i = 0; i < num; i++) {
  // 生成私钥
  const privateKey = crypto.randomBytes(32);
  // 生成公钥
  const publicKey = secp256k1.publicKeyCreate(privateKey, false).slice(1);
  // 生成地址
  const address = createKeccakHash("keccak256").update(publicKey).digest().slice(-20);
  const normAddress = toChecksumAddress(address.toString('hex'));
  // 查看结果
  console.log(privateKey.toString('hex'));
  console.log(normAddress);
}

批量生成

node ethGenerator.js
