start_jwt 0.2.0

JSON Web Token implemented as a standard Dart codec.

JSON Web Token

JSON Web Token (JWT) is a compact URL-safe means of representing claims to be transferred between two parties. The claims in a JWT are encoded as a JavaScript Object Notation (JSON) object that is used as the payload of a JSON Web Signature (JWS) structure or as the plaintext of a JSON Web Encryption (JWE) structure, enabling the claims to be digitally signed or MACed and/or encrypted.

The JWT spec is implemented as a standard Dart Codec.

Example usage

import 'package:start_jwt/json_web_token.dart';

void main() {

    // Encode (i.e. sign) a payload into a JWT token.
    
    final jwt = new JsonWebTokenCodec(secret: "My secret key");
    final payload = {
      'iss': 'joe',
      'exp': 1300819380,
      'http://example.com/is_root': true
    };
    final token = jwt.encode(payload);
    print ("Payload : " + payload.toString());
    
    // Validate a token.
    
    jwt.isValid(token);
    
    // Decode (i.e. extract) the payload from a JWT token.
    
    final decoded = jwt.decode(token);
    print ("Decoded : " + decoded.toString());
}

Status

The API is very simple. The intend is to strictly follow Dart conventions, i.e. make the API as 'dartish' as possible while maintaining simplicity. We are open to any suggestions towards that goal.
