Json Web Token (JWT) library for Dart
Meant for usage in our web server library but also perfectly suitable for usage independently. File issues here and see pub.dev page here.
Limitations
- Currently only supports HS256 algorithm
- Not verified to be safe for production
- Not 100% compliant with the JWT standard yet
Getting started
Add dependency
$ dart pub add t_jwt
or add it manually to your pubspec.yaml
file:
dependencies:
t_jwt: ^replace-with-latest-version
Example usage:
import 'package:t_jwt/t_jwt.dart';
void main() {
JWT jwt = JWT('your-secret-here');
Map<String, String> header = {
'alg': 'HS256',
'typ': 'JWT'
};
Map<String, String> payload = {
'name': 'Topography Digital',
'username': 'topography.digital',
};
DateTime expiresAt = DateTime.now().add(Duration(days: 1));
String signed = jwt.sign(header, payload, expiresAt);
bool isVerified = jwt.verify(signed);
// The token
print(signed);
// True or false depending on if the token is valid
print(isVerified);
}
