Passport-Hash

Passport strategy for authenticating with a hash parameter provided by link.

This module lets you authenticate using a hash parameter provided by link in your Node.js applications. By plugging into Passport, hash authentication can be easily and unobtrusively integrated into any application or framework that supports Connect-style middleware, including Express.

Installation

$ npm install passport-hash

Usage

Configure Strategy

The hash authentication strategy authenticates users using a hash link. The strategy requires a verify callback, which accepts this hash and calls done providing a user.

passport.use(new HashStrategy(
  function(hash, done) {
    User.findOne({ hash: hash }, function (err, user) {
      if (err) { return done(err); }
      if (!user) { return done(null, false); }
      if (!user.isUnconfirmed()) { return done(null, false); }
      return done(null, user);
    });
  }
));

Authenticate Requests

Use passport.authenticate(), specifying the 'hash' strategy, to authenticate requests.

For example, as route middleware in an Express application:

app.get('/confirm/:hash', 
  passport.authenticate('hash', { failureRedirect: '/login' }),
  function(req, res) {
    res.redirect('/');
  });

Examples

For a complete, working example, refer to the login example.
