Full Form of JWT
What is JWT?
JSON Web Token (JWT) is an open standard (RFC 7519) for securely transmitting information between parties as a JSON object. It is commonly used for authentication and authorization in web applications and APIs. In India, JWT is widely adopted in e-commerce platforms, banking apps, and government digital services like Aadhaar-based authentication to ensure stateless, scalable user sessions. It consists of three parts: a header, a payload, and a signature, which are Base64URL-encoded and concatenated with dots. The signature verifies that the token has not been tampered with. JWTs are used when a user logs into a system, and the server generates a token that the client stores (often in local storage or cookies) and sends with subsequent requests. This eliminates the need for server-side session storage, making it efficient for distributed systems. For students preparing for computer science or cybersecurity exams, understanding JWT is crucial as it appears in topics like web security, RESTful API design, and authentication protocols. Its self-contained nature and compatibility with mobile and web platforms have made it a cornerstone of modern Indian tech infrastructure.
