Get Certificate Chain Certs

See more Certificates Examples

Demonstrates how to get the certs in the chain of authentication for a certificate loaded from the Windows certificate store. Dart

import 'package:chilkat/chilkat.dart';

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

  // This example will get the SSL server certificate for tools.chilkat.io
  // which we happen to have locally installed in our Windows certificate store.
  try {
    cert.loadByCommonName('tools.chilkat.io');
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  final chain = CkCertChain();
  try {
    cert.buildCertChain(chain);
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  final certInChain = CkCert();
  final numCerts = chain.numCerts;
  var i = 0;
  while (i < numCerts) {
    chain.certAt(i, certInChain);
    print('${i + 1}: ${certInChain.subjectCN}');

    // Get this certificate in base64 format
    final b64 = certInChain.getEncoded();
    print(b64);

    i++;
  }
