JWT INSPECTOR

A JSON Web Token (JWT) consists of three parts separated by dots (.):

• Header: Defines the algorithm (e.g. HS256) and token type (JWT).
• Payload: Contains standard and custom claims like iss (issuer), sub (subject), aud (audience), iat (issued at), and exp (expiration time).
• Signature: Used to verify the message wasn't changed along the way.

Safe Decoding: Base64URL decoding is executed client-side without sending tokens to any server. Signatures can be verified using HMAC-SHA256 if you provide the shared secret.
