buffer-equal-constant-time
Constant-time Buffer comparison for node.js. Should work with browserify too.
npm install buffer-equal-constant-time
Usage
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:
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():
require('buffer-equal-constant-time').restore();
