Tag: How do you decode JWT in flutter?

JWT Decoder This is a small library for decoding a json web token for dart / flutter . Since the header and payload is base64 encoded you can easily know the stored data with no password, you can also know if the token is expired or not.

JWT, or JSON Web Token, is an open standard used to share security information between two parties — a client and a server . Each JWT contains encoded JSON objects, including a set of claims. JWTs are signed using a cryptographic algorithm to ensure that the claims cannot be altered after the token is issued.

What is a JWT? JSON Web Tokens are an open and standard (RFC 7519) way for you to represent your user’s identity securely during a two-party interaction . That is to say, when two systems exchange data you can use a JSON Web Token to identify your user without having to send private credentials on every request.
