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>
|
||
|
|
```
