[ ] Implement User Entity: Define a Java entity class for users with attributes such as username, password, email, roles, etc.
[ ] User Registration Endpoint: Create a RESTful API endpoint for user registration. Implement validation logic to ensure that the registration data is valid.
[ ] User Authentication Endpoint: Create a RESTful API endpoint for user authentication (login). Implement authentication logic to verify user credentials.
[ ] Token Generation: Implement token generation logic upon successful user authentication. Use JWT (JSON Web Tokens) or other suitable token-based authentication mechanisms.
[ ] Authorization Mechanisms: Set up authorization mechanisms to control user actions based on roles (e.g., user, admin). Define user roles and permissions.
[ ] Secure Endpoints: Secure API endpoints to ensure that only authenticated and authorized users can access certain operations (e.g., updating user profile, deleting user account).
[ ] Password Hashing: Implement password hashing to securely store user passwords in the database. Use bcrypt or other secure hashing algorithms.
[ ] Session Management: Implement session management mechanisms to handle user sessions securely. Consider techniques such as session tokens, session expiration, etc.
[ ] Password Reset Functionality: Implement password reset functionality to allow users to reset their passwords securely in case they forget them.
[ ] User Profile Endpoint: Create a RESTful API endpoint for retrieving and updating user profiles. Implement authorization logic to ensure that users can only access and update their own profiles.
[ ] Integration Testing: Write integration tests to ensure that the authentication and authorization mechanisms work as expected under different scenarios.
[ ] Documentation: Document the authentication and authorization mechanisms, including how to register users, authenticate users, obtain tokens, and secure endpoints.
[ ] Code Review: Request code reviews from team members to ensure code quality, adherence to security best practices, and maintainability.
[ ] Refactoring and Optimization: Identify and address any areas for refactoring or optimization to improve the security and performance of the authentication and authorization mechanisms.
