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();
