Fast Auth

A simple yet fast Token Authorization / Authentication method. No need for bulky modules

This module is lightwight and simply gets straight to the point of creating and authorizing tokens with expiry built in.

Main functions & Features

Features	Description
`createToken(payload,secret)`	This simply encodes our payload *data to base 64 and signs the token using hmac sha256 for productive security 2018
`authToken(token, secret)`	This will check the token is valid and that the data has not been tampered with.
`expiry` default `9000000` 2.5hrs	You can set your own expiry by using `createToken(payload,secret,expiry)`
Authorization: Bearer	This currently works using tokens that contain Bearer, see examples to add this so it will also parse your token if not.

Requires

Uses crypto for the hmac sha256 token signing.

Example Usage

Creating a token

// Require our module.
const auth = require('fastauth');

let secret = '3748238949jkfndkcvniwe733' // Please use a secure secret.
userID = '1',
userName = 'AdminTest',
email = 'admin@test.com',
custom = 'custom',
expiry = 3000000,

payload = `
    "user": {
        "_id":"${userID}",
        "username":"${userName}",
        "email":"${email}",
        "custom":"${custom}"

Authenticating a token

// Require our module.
const auth = require('fastauth');

let token = req.headers['authorization']; // OR
// If the token has does not have Bearer use
let token = `Bearer ${token from req}`;

let isAuth = auth.authToken(checkToken, secret);
// If isAuth...
if(isAuth)
    // Do stuff after the token has been verified.
    console.log(`You're token is valid! Data: ${token}`);
else
    // Invalid token.
    console.log(`Invalid Token!`);
