-title: ECIES
-description: Uses ECIES symmetric key negotiation from public keys to encrypt arbitrarily long data streams.
----
-# ECIES
-
-## Description
-
-Bitcore implements [Elliptic Curve Integrated Encryption Scheme (ECIES)](http://en.wikipedia.org/wiki/Integrated_Encryption_Scheme), which is a public key encryption system that performs bulk encryption on data using a symmetric cipher and a random key.
-
-For more information refer to the [bitcore-ecies](https://github.com/bitpay/bitcore-ecies) github repo.
-
-## Installation
-
-ECIES is implemented as a separate module and you must add it to your dependencies:
-
-For node projects:
-```
-npm install bitcore-ecies --save
-```
-
-For client-side projects:
-```
-bower install bitcore-ecies --save
-```
-
-## Example
-
-```
-var bitcore = require('bitcore');
-var ECIES = require('bitcore-ecies');
-
-var alicePrivateKey = new bitcore.PrivateKey();
-var bobPrivateKey = new bitcore.PrivateKey();
-
-var data = new Buffer('The is a raw data example');
-
-// Encrypt data
-var cypher1 = ECIES.privateKey(alicePrivateKey).publicKey(bobPrivateKey.publicKey);
-var encrypted = cypher.encrypt(data);
-
-// Decrypt data
-var cypher2 = ECIES.privateKey(bobPrivateKey).publicKey(alicePrivateKey.publicKey);
-var decrypted = cypher.decrypt(encrypted);
-
-assert(data.toString(), decrypted.toString());
-```
