Using JWE to cryptographically protect JWT tokens
This recipe will present an advanced topic related to JWT architecture, which is JSON Web Encryption (JWE). As you have seen before in the previous recipes of this chapter, we were using the JSON Web Signature (JWS) approach, which promotes integrity protection. With JWE, we start providing confidentiality to JWT tokens issued by the Authorization Server. This recipe is important to learn so you can add another layer of security for your application.
Getting ready
To run this recipe, you will need to create a Spring Boot application to configure the Authorization Server using Java 8, MySQL, Maven, and the library Nimbus JOSE + JWT. The other dependencies will be described in the How to do it... section.
Note
Nimbus JOSE + JWT, by Connect2id is an open source library that will help us to effectively work with JWT.
How to do it...
This recipe shows you how to create the Authorization Server that will be defined as the jwe-server
project. This project...
