ASP.NET Core Web API: Login & Register with JWT Token Functionality

This project is a demonstration of implementing user authentication and authorization in an ASP.NET Core Web API using JSON Web Tokens (JWT). It provides endpoints for user registration, user login, and accessing protected resources by validating JWT tokens.

Features

• User Registration: Allows new users to create an account by providing necessary details such as username, email, and password.
• User Login: Provides an endpoint for existing users to authenticate themselves by providing their credentials (username/email and password).
• JWT Token Generation: Upon successful authentication, the server generates a JWT token containing user information and returns it to the client.
• JWT Token Validation: Protected endpoints require clients to include a valid JWT token in the Authorization header. The server validates the token to ensure the user has the necessary permissions to access the requested resource.

Technologies Used

ASP.NET Core: The primary framework for building web applications and APIs.

C#: The programming language used for backend logic and API.

JWT (JSON Web Tokens): Used for secure token generation and authentication.

Swagger UI: A tool to document and test APIs.

PostgreSQL: A lightweight, file-based database used for local development and testing.
