    Project mention: Learning JWT security using KumuluzEE — The finances of a league of the environment | dev.to | 2024-12-27

    We have reached the end of our session. Thank you for following this. We can see how JWT tokens are compact and very much less verbose than their XML counterpart, the SAML tokens. We have seen how easy it is to create and use tokens to get certain authorizations needed for certain methods and how we get there via a signed token. I find however very important to get an idea of how JWT works. Hopefully, with this, I have given you a good introduction to how JWT tokens work. To get a better idea of how all of this works, I advise you to play around with the implemented cypress tests. This is a great way to see how requests are being made and what we are testing and what is expected. Then you’ll also get a better idea of why some users get to perform certain operations and others don’t. I have placed all the source code of this application on GitHub I hope that you have enjoyed this article as much as I enjoyed writing it. Thank you for reading!
