This module links an authentication function with a token generation
node-tokauth is a simple node.js module that links an authentication process with a token generation. It uses a hash to generate a token, that is based on a key provided by the developer. So, the unicity of the generated token is on the developer's own.
The user can set the used algorithm, and the based key generation. And, of course, the authentication function that will be executed.
You can either clone this repo, either install this module via npm:
$ npm install tokauth
var Tokauth = require'tokauth';// Build the object with the authentication functionvar tokauth =return username === 'test' && password === 'test';;// Specify the key onto will be based the hashing process// Here, we base it on the username, the password, and the timestamptokauthkey = 'test' + 'test' + getTime;// Generates the tokenvar token = tokauthgetTokenusername password;if tokenconsole.log"Generated token: " + token;elseconsole.log"Authentication failed";
There're two main things to know about the function you'll provide to the Tokauth object:
- It MUST return a boolean value
- It can accept as many arguments as needed, it's on your own
Please, be aware that this attribute will affect the generated token unicity. If you base your key on the password, it's dangerous, as it's possible that two users have the same one. But, if you base it on a concatenation between the username, its password and the time of the authentication, then, your key has more chances to be unique.
