OAuth 2.0 Cookbook

By: Adolfo Eloy Nascimento

Overview of this book

OAuth 2.0 is a standard protocol for authorization and focuses on client development simplicity while providing specific authorization flows for web applications, desktop applications, mobile phones, and so on. This book also provides useful recipes for solving real-life problems using Spring Security and creating Android applications. The book starts by presenting you how to interact with some public OAuth 2.0 protected APIs such as Facebook, LinkedIn and Google. You will also be able to implement your own OAuth 2.0 provider with Spring Security OAuth2. Next, the book will cover practical scenarios regarding some important OAuth 2.0 profiles such as Dynamic Client Registration, Token Introspection and how to revoke issued access tokens. You will then be introduced to the usage of JWT, OpenID Connect, and how to safely implement native mobile OAuth 2.0 Clients. By the end of this book, you will be able to ensure that both the server and client are protected against common vulnerabilities.

Using JWE at the Resource Server side

This recipe will show you how to create a Resource Server that is able to validate JWE access tokens. By using this recipe you will also be able to understand important extension points provided by Spring Security OAuth2 and how to integrate other libraries such as Nimbus to allow cryptography.

Getting ready

To run this recipe, you will need to create a Spring Boot application to configure the Resource Server using Java 8, Maven, Spring Web, Spring Security, and Nimbus JOSE + JWT. Some dependencies will be described in the How to do it... section.

How to do it...

This recipe presents you with how you can create the Resource Server that will be defined as the project jwe-resource. This project is available on GitHub in the Chapter05 folder and all you need to create this project is presented in the following steps:

  1. You can create the project jwe-resource at Spring Initializr, referencingWebandSecuritydependencies to easily set up the project.
  2. If you have created...
