JWT (JSON Web Token) is an open standard for securely transmitting information between web applications. It consists of three parts: Header, Payload, and Signature, separated by dots.

• 📌 Header: Contains the token type and signing algorithm (e.g., HMAC, RSA).
• 📌 Payload: Contains claims such as user ID, expiration time, etc.
• 📌 Signature: Used to verify that the message has not been tampered with (this tool does not verify signatures).
• 🔐 JWT uses Base64URL encoding (replaces + and / with - and _, and removes padding =).
• 💡 Enter a valid JWT token and click "Decode" to view the raw JSON of the Header and Payload.
