# ECIES for Bitcore-Dash

[![Build Status](https://img.shields.io/travis/dashpay/bitcore-ecies-dash.svg?branch=master&style=flat-square)](https://travis-ci.org/dashpay/bitcore-ecies-dash)

A module for [bitcore-dash][bitcore-dash] that implements the [Elliptic Curve Integrated Encryption Scheme (ECIES)][ECIES]. Uses ECIES symmetric key negotiation from public keys to encrypt arbitrarily long data streams.

See [the main bitcore-dash repo](https://github.com/dashpay/bitcore-dash) or the [bitcore guide on ECIES](http://bitcore.io/guide/module/ecies/index.html) for more information.

Credit to [@ryanxcharles][ryan] for the original implementation.

## Getting started

ECIES will allow to securely encrypt and decrypt messages using ECDSA key pairs (bitcoin cryptography).

```javascript
var alice = ECIES()
  .privateKey(aliceKey)
  .publicKey(bobKey.publicKey);

var message = 'some secret message';
var encrypted = alice.encrypt(message);

// encrypted will contain an encrypted buffer only Bob can decrypt

var bob = ECIES()
  .privateKey(bobKey)
  .publicKey(aliceKey.publicKey);
var decrypted = bob
  .decrypt(encrypted)
  .toString();
// decrypted will be 'some secret message'
```
