crypto-wallets

Javascript/Node library for generating cryptocurrency addresses and private keys.

Supported Currencies:

• Bitcoin (BTC)
• Bitcoin Cash (BCH)
• Dogecoin (DOGE)
• Ethereum (ETH)
• IOTA (IOTA)
• Litecoin (LTC)
• Monero (XMR)
• Namecoin (NMC)
• Peercoin (PPC)
• Tezos (XTZ)

Usage

Install crypto-wallets with npm install --save crypto-wallets

Example: Generate Bitcoin Wallet

var cw = require('crypto-wallets');
var bitcoinWallet = cw.generateWallet('BTC');
console.log("Address: " + bitcoinWallet.address);
console.log("Private Key: " + bitcoinWallet.privateKey);

Example: Generate Ethereum Wallet

var cw = require('crypto-wallets');
var ethWallet = cw.generateWallet('ETH');
console.log("Address: " + ethWallet.address);
console.log("Private Key: " + ethWallet.privateKey);

Example: Generate Monero Wallet

Note: Generating Monero (XMR) and IOTA (IOTA) wallets are both asynchronous and return a promise, unlike the other currencies.

var cw = require('crypto-wallets');
cw.generateWallet('XMR').then(function(moneroWallet){
    console.log("Address: " + moneroWallet.address);
    console.log("Private Key: " + moneroWallet.privateKey);
});

CLI - Command Line Interface

crypto-wallets can also be used in the command line.

Commands:

generate <currency> [number] [--save <file>]

Generates and prints wallets in given currency. If [number] is not given, it defaults to 1. If the optional --save flag is provided, the generated wallets will be saved to the specified file in CSV format.

Generate bitcoin wallet

>crypto-wallets generate btc
[ { currency: 'BTC',
    privateKey: 'L3Qa2u7nkHaNYZdsQYi2gVmBEtpppk4JrvQqaSYx51HWG51uwaTa',
    address: '1HMt2J3dQE428krHQEmFRFNDv2DyGAaMfb' } ]

Generate 3 dogecoin wallets

>crypto-wallets generate doge 3
[ { currency: 'DOGE',
    privateKey: 'QWgiPqSPNXTtTt32hffy8C1uvHT4BJcbo78TSJcEmvf6AyhE85L3',
    address: 'DJnvD1NxRjgmXKGbCR98QEneFYcGGmnquc' },
  { currency: 'DOGE',
    privateKey: 'QPfrc7ahUuXqqd8oeETGh4ZzCrS1wNhognEx4N5my6MK3e6qQh1o',
    address: 'DN6uQWUNDfzjsXdaTtMhxwRK4hZ4RJJ357' },
  { currency: 'DOGE',
    privateKey: 'QTgfpCVt8CW1bgw9PdfmsSNY1FKodM65bLYYkQeaoqm1CkNgD3MK',
    address: 'DC7xVTob9XE6Soy6TjeWySinS3hG4cjR3F' } ]

Generate 100 monero wallets and save them to 'xmrWallets.csv'

>crypto-wallets generate xmr 100 --save xmrWallets.csv
Successfully saved to file: xmrWallets.csv

verify <currency> <privateKey> <address>

Checks if the given private key controls the given address.

>crypto-wallets verify doge QWgiPqSPNXTtTt32hffy8C1uvHT4BJcbo78TSJcEmvf6AyhE85L3 DJnvD1NxRjgmXKGbCR98QEneFYcGGmnquc
Success: The private key matches the address

>crypto-wallets verify btc foo bar
Failure: The private key does not match the address

Security

This library uses other third party libraries to generate the cryptocurrency addresses. So this library is secure if you trust the other libraries.

The libraries used are:

• Bitcoin: coinkey
• Bitcoin Cash: bitcore-lib-cash
• Dogecoin: coinkey
• Ethereum: ethereumjs-wallet
• IOTA: iota.lib.js, seed is generated with custom code using Node's crypto library
• Litecoin: coinkey
• Namecoin: coinkey
• Peercoin: coinkey
• Tezos: tezos-sign
• Monero: mymonero
