Encoding/issuing JWT token

final encoder = new AuthenticationConf.SymmetricKey(
  'dfsdffasdfdgdfgdfg456456456', 'teja',
  audience: <String>['admin', 'students']);

ClaimSet claimSet =
  new ClaimSet('kleak', encoder.issuer, encoder.audience, {'k': 'v'});
String encoded = encoder.encodeClaimSet(claimSet);
print(encoded);

Decoding JWT token

final decoder = new AuthorizationConf.SymmetricKey(
  'dfsdffasdfdgdfgdfg456456456', 'teja',
  audience: <String>['students']);
JsonWebToken decoded = decoder.decodeToken(encoded);
print(decoded.claimSet.toJson());
