About

This repository is made to provide code samples used in the post I created for wannabedev.io titled "Everything you need to know about JSON Web Token". You can find the whole blog post here.

How to run

I recommend reading the article first and then coming back to experiment with the code. This example uses the jose npm module. Make sure to install the required dependencies by running:

npm install

RSA keys are already created and stored in the keys directory. There, you can find public and private keys.

keys
├── private.pem
└── public.pem

In case you want to create new RSA keys, you can use generate-rsa-key-pair.js and generate a new pair by running:

node generate-rsa-key-pair.js

To get the fresh JWT, run the following command:

node authentication-server.js

Copy the token and modify userToken by providing the newly generated token. After that, run the following command to verify the token:

node application-server.js

Feel free to experiment with token configurations in authentication-server.js and see how they affect token verification in application-server.js.

This repository is only made for learning purposes; do not use it in production or commercial projects.
