Example: Crypt2.ClearSigningCerts method

Demonstrates how to call the ClearSigningCerts method. Dart

import 'package:chilkat/chilkat.dart';

void main() {
  final crypt = CkCrypt2();

  // Tell the crypt object to use 3 certificates.
  // Do this by calling AddSigningCert for each certificate.

  final cert1 = CkCert();
  // ...
  // Load the cert from a source such as a .pfx/.p12 file, smart card, USB token, Apple keychain, Windows certificate store, etc.
  // ...
  crypt.addSigningCert(cert1);

  final cert2 = CkCert();
  // ...
  crypt.addSigningCert(cert2);

  final cert3 = CkCert();
  // ...
  crypt.addSigningCert(cert3);

  final bd = CkBinData();
  // ...

  crypt.opaqueSignBd(bd);

  // Let's say we now want to sign something else with different certs..
  // First clear the signing certs.
  crypt.clearSigningCerts();

  final cert4 = CkCert();
  // ...
  crypt.addSigningCert(cert4);

  final cert5 = CkCert();
  // ...
  crypt.addSigningCert(cert5);

  // ...
  // ...

  // Sign using cert4 and cert5.
  crypt.opaqueSignBd(bd);
