JWT VS frank_jwt

To authenticate our users, we need to add jwt gem to our Gemfile

jwt is a Ruby implementation of the RFC 7519 OAuth JSON Web Token standard. bcrypt is a Ruby binding for the OpenBSD bcrypt() password hashing algorithm.

ruby-jwt is fairly easy to use on it's own without Devise. You might try that first and only add Devise if needed.

Generally speaking, the larger the application, the more internal and external services it has to talk to. External services usually have their own way of authenticating and authorizing third party API calls. With internal systems however, organisations prefer to use JWT tokens because of their inherent flexibility and versatility. A sample JWT based handshake between 2 rails applications using ruby-jwt would look like this -

Interesting. What's the difference between this and the standard ruby-jwt? https://github.com/jwt/ruby-jwt

jwt - encoding and decoding jwt oauth

Decoding JWTs is simple whit the help of an already implemented solution. In this section, I'll be using the ruby-jwt.

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.

Se pegar o token jwt podemos ver o que tem dentro, usando o site jwt.io.
