A **JWT** (pronounced "jot") stands for **JSON Web Token**. It's a compact, URL-safe means of representing claims to be transferred between two parties. Essentially, it's a way for a server to issue an access token to a client, which the client can then use to prove its identity and access protected resources, without the server having to store a session record for every client. Think of it like a **digital, signed ID card or a special event ticket**. It contains information about who you are, what permissions you have, and is sealed with a signature to prove it hasn't been tampered with and was issued by a legitimate source. --- ### How a JWT works and its structure: A JWT is typically a long string of characters, separated by dots (`.`) into three parts: `xxxxxxxxxx.yyyyyyyyyy.zzzzzzzzzz` 1. **Header:** * **What it contains:** Metadata about the token itself, like the type of token (JWT) and the signing algorithm used (e.g., HS256, RS256). * **Example (JSON):** ```json { "alg": "HS256", "typ": "JWT" } ``` * This JSON is then **Base64Url encoded**. 2. **Payload (Claims):** * **What it contains:** The actual data or "claims" about the entity (usually the user) and any additional metadata. Claims are statements. * **Types of Claims:** * **Registered Claims:** Pre-defined, standard claims (e.g., `iss` for issuer, `exp` for expiration time, `sub` for subject, `iat` for issued at time). * **Public Claims:** Custom claims defined by those using JWTs, but designed to avoid collisions (e.g., using an IANA Registry or a URI that acts as a namespace). * **Private Claims:** Custom claims created for specific agreement between parties (e.g., `userId`, `role`, `admin`). * **Example (JSON):** ```json { "sub": "1234567890", "name": "John Doe", "admin": true, "iat": 1516239022, "exp": 1516242622 // Expiration time } ``` * This JSON is also **Base64Url encoded**. 3. **Signature:** * **What it contains:** A cryptographic signature used to verify that the sender of the JWT is who it says it is and to ensure that the message hasn't been tampered with. * **How it's created:** The signature is created by taking the **encoded Header**, the **encoded Payload**, a **secret key** (known only by the server), and applying the algorithm specified in the header (e.g., HMAC SHA256). * `Signature = HMACSHA256(base64UrlEncode(header) + "." + base64UrlEncode(payload), secret)` * **Crucial Point:** The payload is **not encrypted** by default. It's just encoded. Anyone can decode the header and payload to read the information inside. The signature only ensures its *integrity* and *authenticity*, not *confidentiality*. If you need confidentiality, you'd use JWE (JSON Web Encryption) or encrypt the payload yourself. --- ### How JWTs are used in authentication: 1. **Login:** User
