xor-stream-cipher v0.0.2

xor-stream-cipher

A simple xor stream cipher. Uses seed-bytes for the key stream.

Get it!

npm install --save xor-stream-cipher

Usage

var XOR = require('xor-stream-cipher')
var thru = require('stream').PassThrough()

var plain = 'the money is in the attic'
var shared = '419'
var a = XOR(shared)
var b = XOR(shared)

function ondata (name, chunk) {
  console.log(name + ':', chunk.toString())
}

a.pipe(thru).pipe(b)

a.on('data', ondata.bind(null, 'alice'))
b.on('data', ondata.bind(null, 'bob'))

a.end(plain)

API

XOR(init[, algo])

Create a new XOR stream. init is the seed for a random byte generator used as key stream. algo indicates the algorithm to use for the internal random number generator, defaults to 'alea'. Check out seedrandom for a list of supported algorithms.
