Compress EBICS SignaturePubKeyOrderData XML

See more EBICS Examples

This example provides a note about how to compress the SignaturePubKeyOrderData XML for EBICS. Dart

import 'package:chilkat/chilkat.dart';

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

  // We have this XML to be compressed and then encoded in Base64.
