EOS Encrypt

Allows to encrypt & decypt a message with an EOS key pair using AES shared key encryption mechanism.

Decryption is achieved by combining the receiver's private key and the sender's public key to create the private key necessary to decrypt the message.

This module uses eosjs-ecc to perform the required cryptographic operations.

Install

npm

$ npm install --save eos-encrypt

Usage

import { encrypt, decrypt } from 'eos-encrypt';

const public_key = "EOS6M...DW5CV";
const private_key = "5KQwr...zkvFD3";

const message = "Private Message, shhhh!";
const encrypted = encrypt(private_key, public_key, message);
// => TO DECRYPT: eos-encrypt
// .1167451677...23460624..862584768Q+h1AeLQbjfzZJD1Nsx6kk3U/jSNStwoWstz9uNCadw=

const decrypted = decrypt(private_key, public_key, encrypted);
// => Private Message, shhhh!
