A dart implementation of the famous javascript library 'jsonwebtoken' (JWT).
JSON Web Token (JWT) #
A dart implementation of the famous javascript library jsonwebtoken
.
JSON Web Tokens are an open, industry standard RFC 7519 method for representing claims securely between two parties.
https://jwt.io allows you to decode, verify and generate JWT.
Usage #
Import #
import 'package:dart_jsonwebtoken/dart_jsonwebtoken.dart';
Sign #
// Create a json web token
final jwt = JWT(
{
'id': 123,
'server': {
'id': '3e4fc296',
'loc': 'euw-2',
}
},
issuer: 'https://github.com/jonasroussel/jsonwebtoken',
);
// Sign it (default with HS256 algorithm)
token = jwt.sign(SecretKey('secret passphrase'));
print('Signed token: $token\n');
Verify #
try {
// Verify a token
final jwt = JWT.verify(token, SecretKey('secret passphrase'));
print('Payload: ${jwt.payload}');
} on JWTExpiredError {
print('jwt expired');
} on JWTError catch (ex) {
print(ex.message); // ex: invalid signature
}
