A simple module for bitwise-xor on buffers.


## Examples

``` javascript
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>
```


Or for those seeking those few extra cycles, perform the operation in place:

``` javascript
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>
// NOTE: xorInplace will return the shorter slice of its parameters

// See that a has been mutated
console.log(a)
// => <Buffer f0 0f 0f>
```
