 | 
						|
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>
 | 
						|
```
