CherryPy - Interview Questions
How does CherryPy support authentication and authorization in web applications?
Authentication in CherryPy :

* Basic Authentication : CherryPy offers basic authentication mechanisms using HTTP's basic authentication method. Developers can implement basic authentication by defining a method to check credentials and use decorators to protect specific endpoints.
import cherrypy

class ProtectedResource:
    @cherrypy.expose
    @cherrypy.tools.auth_basic(realm='MyRealm')
    def secure_endpoint(self):
        # Endpoint accessible only with valid credentials
        pass​

* Custom Authentication : Developers can implement custom authentication mechanisms by creating their own authentication tools or using middleware to authenticate requests based on various criteria like tokens, session information, or custom authentication backends.

Authorization in CherryPy :

* Role-Based Access Control (RBAC) : CherryPy allows developers to implement role-based authorization by associating specific roles with users. This can be managed within the application logic by checking a user's role before granting access to certain resources.
import cherrypy

class ProtectedResource:
    @cherrypy.expose
    @cherrypy.tools.authorize(groups=['admin'])
    def admin_section(self):
        # Accessible only to users with 'admin' role
        pass​

* Custom Authorization Logic : Developers can implement custom authorization logic within their CherryPy application, controlling access to specific endpoints or resources based on custom criteria beyond roles, such as user attributes or conditions.
