aion-keystore

This package is derived from a unreleased version of aion-web3 1.0. The features here were tested to be functioning correctly. Currently, aion-web3 1.0 does not inherit all properties of this package. Therefore this package will continue to be maintained.

The functionality that this package provides are:

• Signing transactions (client side)
• Deriving Account information (publicKey, address)
• Import Aion keystore from RLP encoded Buffers
• Export Aion keystore to RLP encoded Buffers

Installation

Node.js

npm install aion-keystore

Usage

Basics

// in node.js
const Accounts = require('aion-keystore');

const account = new Accounts();
const acc = account.create();

// output
acc = {
  _privateKey: Buffer,
  _publicKey: Buffer,
  privateKey: '0xce48884694409e26535e1a6e4e9d21747acdf2d59be910397af31f42de6fd1241ca54b71d7567a0eb6949031eeb3948f9ad7dc6f0689cdbccfff1b7cfc2b9139',
  publicKey: '0x1ca54b71d7567a0eb6949031eeb3948f9ad7dc6f0689cdbccfff1b7cfc2b9139',
  address: '0xa0a3b5b5fc4957cdd15aaec7ec7c968b81e617ca8ad763a2ca7494a6a70ac6e3',
  signTransaction: function(),
  sign: function(),
  encrypt: function(),
  encryptToRlp: function() 
};

Signing Transactions (Promise)

// in node.js
const privateKey = "0xefbc7a4bb0bf24624f97409473027b62f7ff76e3d232f167e002e1f5872cc2884dcff097bf9912b71d619fc78100de8cf7f55dfddbc2bf5f9fdc36bd670781ee";
const accs = new Accounts();

// load account from private key
const acc = accs.privateKeyToAccount(privateKey);

// construct transaction payload
const transaction = {
  to: "0xa050486fc4a5c236a9072961a5b7394885443cd53a704b2630d495d2fc6c268b",

  value: new BN("1000000000000000000"),
  nonce: 1,
  timestamp: 1535399697
};

acc.signTransaction(transaction)
.then((signed) => {
  console.log(signed);
  // outputs

  console.log(res);
  // outputs same as above (promise example)
});
