buffer-equal-constant-time

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

Build Status

  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();
