ECIES for Bitcore-Help
A module for bitcore-help 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-help 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'Contributing
