# OIDC Java Fat-Client Demo

This repository contains a small demo about how to authenticate a java client application

with [OpenID Connect](https://openid.net/connect/) and

the [OAuth2 Authorization Code Flow with PKCE](https://www.rfc-editor.org/rfc/rfc7636).

It was part of my Talk at the JUG Nürnberg. The slides are available on SlideShare: 

## Run the demo

### Keycloak Setup

1. Start keycloak locally using docker or podman as described in the Keycloak

   documentation: 

2. Login into the admin console

3. Create a new OIDC Client named `java-demo`:

   ![create client](docs/images/create-client-step1.png)

   and

   ![create client step 2](docs/images/create-client-step2.png)

4. Add the redirect uri `http://localhost:*`:  

   ![Add redirect uri](docs/images/set-redirect-url.png)

### Run Demo

Run the class `de.chrfritz.oidc.auth.CliTestClient` in `src/test/java`. The example shows the

Run-Configuration for IntelliJ:

![IntelliJ Run Config](docs/images/intellij-runconfig.png)

Then a browser window should be opened:

![Login-Screen](docs/images/login-screen.png)

After a successful login, you should see that the demo got a valid access token and got the

information from the user info endpoint:
