balu.pizza.webapp.security.JwtUtil

@Component
public class JwtUtil
extends Object

A class for generating and validating JWT-token

When accessing through the project's REST API, authentication is required. If authorization is successful, a generated, unique JWT token is returned to the user in the response. By adding this token to the header of all subsequent requests, the user can confirm that the requests come from an authorized user.

The token has a validity of 60 minutes. If the user wants to interact with the server for longer, he/she needs to reauthorize and get a new token
