JWT Authentication API in ASP.NET Core

This project is a simple JWT-based authentication API built with ASP.NET Core. It allows users to register and log in securely, returning a JSON Web Token (JWT) that can be used to authenticate further API requests.

Features

• User registration and login
• JWT-based authentication
• Minimal API setup with ASP.NET Core
• Swagger UI for testing endpoints
• Clear structure and easy to extend

Technologies Used

• ASP.NET Core 6 / 7
• JSON Web Tokens (JWT)
• C#
• Swagger / Swashbuckle for API documentation

How JWT Authentication Works

1. A user registers with a username and password.
2. The user then logs in, and the server returns a JWT token.
3. The client can include this token in the Authorization header for future requests to access protected endpoints.
