ECIES for Bitcore-Dash

A module for bitcore-dash that implements the Elliptic Curve Integrated Encryption Scheme (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 for the original implementation.

Getting started

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

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'
