A certificate contains information about its issuer. This example demonstrates how to get the issuer information from a certificate. Dart

import 'package:chilkat/chilkat.dart';

void main() {
  final cert = CkCert();

  try {
    cert.loadFromFile('qa_data/certs/sample.cer');
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  // Get issuer information:
