How JWT Generation Works
Understanding the process of creating secure tokens
Header
The header specifies the signing algorithm (e.g., HS256) and the token type. It is Base64URL-encoded to form the first part of the JWT.
Payload
The payload contains claims about the entity (typically the user) and additional metadata like expiration time, issuer, and custom data.
Signature
The signature is created by signing the encoded header and payload with a secret key using the specified algorithm, ensuring token integrity.
