Examines the contents of a .p7m signature by converting it to XML. 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 asn = CkAsn();

  try {
    asn.loadBinaryFile('qa_data/p7m/a.p7m');
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  // Convert to XML.
  final strXml = asn.asnToXml();

  // The XML returned by AsnToXml will be compact.
  // To get the XML indented in human-readable form, load
  // into the Chilkat XML object and emit..
  final xml = CkXml();
  xml.loadXml(strXml);

  print(xml.getXml());
  xml.saveXml('qa_output/a.xml');
