# JwtAuthRenewWebApi

A sample project for adding JWT authentication and sliding expiration support in Web API 2.

### Background

I like JWT. I think it is a simple and elegant solution for authenticating REST / AJAX / Web API calls.
For some time now I've been urging anyone who will listen to switch their single-page-application (SPA) websites to use JWT for authentication and state instead of cookies and session.

For those unfamiliar with it, however, it can be scary, confusing, and even difficult to integrate into their new / existing projects based on some of the scattered resources and documentation out there.
This sample project is meant to illustrate that it is in fact quite simple.

### Project Status

**Done!** Just follow the instructions below for downloading and running the sample project and read the linked documentation if you want a better understanding of how it all works.

## Features

* Demonstrates validation and authentication using JWT
* Demonstrates sliding expiration / renew / reissue token
* Demonstrates custom claims and how JWT can be used in place of session / cookies
* Works with existing Web API authentication, including the `[Authorized]` attribute
* Uses Microsoft's JSON Web Token Handler library -- a well tested and authoritative source for JWT support in Web API
* Well documented code and examples, including how to write a custom `IAuthenticationFilter` and `DelegatingHandler`
* IIS hosting
* Stepping stone to OAuth(2)

*The project is written to use the Web API 2 pipeline and IIS hosting, but the concepts are easily adaptable to a self-hosted OWIN type project.*

## Using the Sample

Clone or download the repo and open it in Visual Studio and hit `F5` to run (nuget packages should automatically be restored).
That should fire-up the project in Visual Studio's (IIS Express) development server (on port 30908?).

The meat and potatoes of what you want are in the `UsersController.cs`, `BearerAuthenticationFilter.cs`, and `SlidingExpirationHandler.cs` files.

To see how JWTs are exchanged from browser to server and vice versa, open the `Example.html` file in the site root (`http://localhost:30908/example.html`).
This file has a little jQuery in it to demonstrate some of the API calls with and without JWT authentication.
Using your Chrome Developer Tools and Visual Studio, trace some of the API calls.

Study the code.
Read the docs.
Learn.

## Documentation

I tend to over explain things. To that end, there is more documentation explaining the code than there is actual code in the project.

* [Issuing a JWT](docs/Issuing-JWT.md)
* [Validating a JWT](docs/Validating-JWT.md)
* [Reissusing a JWT with a New (Sliding) Expiration](docs/Sliding-Expiration.md)

## Credits

The [JwtAuthWebApi](https://github.com/rnarayana/JwtAuthWebApi) project here on GitHub motivated me to create this project.
I liked the idea of a simple project to explain JWT in Web API, but found that project to be outdated and overly complicated.
