Tender provides a mechanism for single sign-on known as Multipass. Multipass uses an AES encrypted JSON hash and node-multipass provides functions for encoding and decoding these tokens.
More details on Multipass can be found here.
npm install multipass
Multipass is constructed with two arguments: an API key and a site key. These keys can be found within the Tender admin (Accounts & Settings > Extras > Single Sign-On).
var Multipass = require('multipass');
// Construct the Multipass encoder / decoder
var multipass = new Multipass('API-KEY', 'SITE-KEY');
// Encode a Multipass token
var token = multipass.encode({ email: '[email protected]', name: 'test', expires: '2011-07-06 23:28:40Z' });
// Decode a Multipass token
var obj = multipass.decode(token);This function encodes the required obj argument. This argument is a JavaScript object and contains the data that you want to pass to Tender. A list of expected keys can be found here.
This function will return a string. If an error occurs, the undefined will be returned.
This function decodes the required token argument. This argument is an encoded Multipass token and a JavaScript object is returned. If decoding is not successful, undefined is returned.
