A simple module for bitwise-xor on buffers.
var xor = require('buffer-xor')
var a = new Buffer('00ff0f', 'hex')
var b = new Buffer('f0f0', 'hex')
console.log(xor(a, b))
// => <Buffer f0 0f 0f>Or for those seeking those few extra cycles, perform the operation in place with
xorInplace:
NOTE: xorInplace won't xor past the bounds of the buffer it mutates so make
sure it is long enough!
var xorInplace = require('buffer-xor/inplace')
var a = new Buffer('00ff0f', 'hex')
var b = new Buffer('f0f0', 'hex')
console.log(xorInplace(a, b))
// => <Buffer f0 0f 0f>
// See that a has been mutated
console.log(a)
// => <Buffer f0 0f 0f>
