About JWT Tokens
JSON Web Tokens (JWT) are a compact, URL-safe means of representing claims securely between two parties.
Structure: A JWT consists of three parts separated by dots: Header.Payload.Signature
Security Note: This tool only decodes the header and payload. The signature verification requires the secret key and should be done server-side.
