php-jwt VS frank_jwt

So basically if the login is successfull I have to create a JWT token (with something like this library) with the userID inside and send it via `setcookie()` for web or in a JSON response to the API client and consider it the long lived refresh token.

This depends on the library you end up downloading for the platform of your choosing. Some of the parts I explained above will be handled by the library for example in my case I decoded signedTransactionInfo using firebase/php-jwt. This has the added benefit of always checking the validity of the signature which was omitted in the manual method.

That's not what JWT is, but I can understand why someone would be misled into believing that.

JWT isn't just an encoding format, it also includes a crypto algorithm negotiation protocol that lets the attacker choose the algorithm. Even if you strictly allow-list which algorithm you want to support, you can accidentally bypass this control in many libraries if you suppor the `kid` (key ID) header. [1]

It also allows attackers to completely strip the security. [2] [3]

Put shortly, JWT is a gun aimed directly at your foot. That's why there's so much hate for JWTs.

NOTE: Never store sensitive information about a client in the payload as the JWT is just encoded and not encrypted. You can paste the JWT I gave as an example above in this cool site which basically allows you to see in decoded. JSON Web Tokens - jwt.io

Although they did not make it into production, I experimented with the RabbitMQ message broker, Python (Django, Flask), Kubernetes + minikube, JWT, and NGINX. This was a hobby project, but I intended to learn about microservices along the way.

JSON Web Token (JWT) creation to extend user authentication to server-side functions

The (probably) most famous web resource about JWT - https://jwt.io - provides such a definition of JSON Web Tokens:

If you want to play with JWT and put these concepts into practice, you can use jwt.ioDebugger to decode, verify, and generate JWTs.

In this context, JSON Web Tokens (JWTs) play a crucial role.

Json Web Token (JWT): Even though it is more like an industry standard, we will use JWTs for stateless authentication in this article. If you want to learn more, you can refer to the official documentation.
