var crypto = require('crypto')
var xsalsa20 = require('xsalsa20')

var nonce = crypto.randomBytes(24)

var xor = xsalsa20(nonce, key)

console.log(xor.update(new Buffer('hello')))
console.log(xor.update(new Buffer('world')))

xor.finalize()

API

var xor = xsalsa20(nonce, key)

Create a new xor instance.

Nonce should be a 24 byte buffer/uint8array and key should be 32 bytes.

var output = xor.update(input, [output])

Update the xor instance with a new input buffer. Optionally you can pass in an output buffer.

xor.finalize()
