buffer-equal-constant-time

Constant-time Buffer comparison for node.js. Should work with browserify too.

sh npm install buffer-equal-constant-time

Usage

```js var bufferEq = require('buffer-equal-constant-time');

var a = new Buffer('asdf'); var b = new Buffer('asdf'); if (bufferEq(a,b)) { // the same! } else { // different in at least one byte! } ```

If you'd like to install an .equal() method onto the node.js Buffer and SlowBuffer prototypes:

```js require('buffer-equal-constant-time').install();

var a = new Buffer('asdf'); var b = new Buffer('asdf'); if (a.equal(b)) { // the same! } else { // different in at least one byte! } ```

To get rid of the installed .equal() method, call .restore():

js require('buffer-equal-constant-time').restore();
