Mar 02, 2020 In this tutorial, we're going to provide an implementation for the OAuth 2.0 Authorization Framework using Jakarta EE And MicroProfile. Most importantly, we're going to implement the interaction of the OAuth 2.0 roles through the Authorization Code grant type.The motivation behind this writing is to give support for projects that are implemented using Jakarta EE as this doesn't yet provide. The JSON Web Key Set (JWKS) is a set of keys which contains the public keys used to verify any JSON Web Token (JWT) issued by the authorization server and signed using the RS256 signing algorithm. When creating applications and APIs in Auth0, two algorithms are supported for signing JWTs: RS256 and HS256.RS256 generates an asymmetric signature, which means a private key must be used to.
Public Private Key Encryption
A simple Java command-line utility created by Justin Richer can be used togenerate keys in JWK format. It supports these key types:
- RSA key
- EC key
- Octet string (symmetric) key
The tool is also available online.
Usage
Invoking the utility without arguments will print its usage message:

Example
To generate a 2048-bit RSA public / private key pair, with a specified key IDand use, and wrapped in a standard JWK set:

The JWK generator will then output a JSON object similar to this:
You can use the above JWK set file to configure your OpenID Connectserver, client, or other application that needs to use orpublish a JWK.
Download
The JWK generator sources can be obtained from its Github repo at
We also provide a ready compiled JAR for the JWK generator:
