Dart Requires Chilkat v11.0.0+

Base64url Encoding

See more Encryption Examples

Base64url encoding is identical to base64 encoding except it uses non-reserved URL characters (e.g. '–' is used instead of '+', and '_' is used instead of '/') and it omits the padding characters. Dart

import 'package:chilkat/chilkat.dart';

void main() {
  // This example requires the Chilkat API to have been previously unlocked.
  // See Global Unlock Sample for sample code.

  final pkey = CkPrivateKey();
  final rsa = CkRsa();
  rsa.genKey(1024, pkey);
  rsa.usePrivateKey(pkey);

  final strData = 'This is the string to be signed.';

  // Get the signature in base64url
  rsa.encodingMode = 'base64url';
  final strSig = rsa.signStringENC(strData, 'sha256');

  print(strSig);
}
