Understanding JWT and Its Implementation in .NET Introduction In modern applications, secure and efficient communication between client and server is essential. JSON Web Token (JWT) has become a popular standard for authenticating and authorizing users. In this blog post, we will explore JWT, understand its structure, and implement it in a .NET application. What is JWT? JWT stands for JSON Web Token , a compact and self-contained method for securely transmitting information between parties as a JSON object. It is widely used in stateless authentication mechanisms in web applications. Key Features: Compact : Suitable for URLs, cookies, and HTTP headers. Self-contained : Contains all necessary information about the user (e.g., claims). Secure : Uses cryptographic signatures to verify authenticity. Structure of a JWT A JWT consists of three parts: Header : Contains the token type ( JWT ) and hashing algorithm (e.g., HS256 ). Payload : Contains claims such as user information and me...
