ECIES for Bitcore-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 or the bitcore guide on ECIES 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'
``
