A nodejs library for validating BrowserID Assertions.


BrowserID is a email based distributed authentication system for the web, supported by Mozilla. Using BrowserID you can allow users to sign into your website with a "verified email address" rather than a traditional username and password. For users sign-in is easier, and for site maintainers it becomes unnecessary to implement password storage and email verification functions.

The BrowserID Verification library

This library verifies BrowserID assertions on a node server locally. The only network requests it makes are to obtain public keys for identity providers, and these keys are aggressively cached. This library is preferred over the mozilla BrowserID service because it can reduce your external dependencies and decrease network latency during sign in. And it's really easy to use.

Getting Started

First, check out the full example client and server in example/. Just npm install && example/main.js, then visit in your browser.

To install:

npm install browserid-verifier

Then implement client code that calls includes https://browserid.org/include.js and calls navigator.id.getVerifiedEmail() when a user clicks your sign-in button. Send the assertion returned from that function up to your server, and verify it in node:

var browseridVerify = require('browserid-verifier');

  assertion: theAssertion,
  audience: "http://mysite.com"
}, function (err, r) {
  // if err is non-falsey, then something went wrong.
  // otherwise, r looks like this:
  //   { email: 'lloyd@mozilla.com',
  //     audience: '',
  //     expires: Fri, 25 Nov 2011 19:55:36 GMT,
  //     issuer: 'browserid.org' }


That is all.
