Xorcrypto NPM | npm.io

xorCrypto

XOR Cipher is secure, as long as key length equal to data length. Simple and lightweight algorithm, this encryption used SHA256 as PRNG to create XOR-KEY.

Features

XOR-KEY will be changed every 32 bytes
XOR-KEY was created from SHA256 of SecrectKey and OpenSSL RNG's value
Simple
Lightweight
Easy to implement
Data don't repeate by sequence
Hash based

Installation

Require NodeJs

npm install xorcrypto

Usage

const xorCrypto = require('xorcrypto');

let myXorCrypto = new xorCrypto(Buffer.from('My secret key, I will share with my friend.'));
let value, encrypted, decrypted;
value = Buffer.from('This is my secret message!');

encrypted = myXorCrypto.encrypt(value);

decrypted = myXorCrypto.decrypt(encrypted);

console.log(`Value: ${value}\nEncrypted: ${encrypted.toString('hex')}\nDecrypted: ${decrypted.toString()}\nIs the same: ${decrypted.toString() == value}`);

Result:
