ScMinidriver - Import Private Key to Smart Card

See more ScMinidriver Examples

Demonstrates how to import a private key to the "signature" or "key exchange" location in the Nth key container on a smart card. Dart

  // This example requires the Chilkat API to have been previously unlocked.
  // See Global Unlock Sample for sample code.

  // Chilkat recommends the following free tool for interactively examining the contents of your smart card
  // through the ScMinidriver interface:  MGTEK Tool for Minidriver enabled Smart Cards

  // Let's first look at our smart card before importing a private key.
  // Here's the view of our Gemalto (Thales) IDPrime MD T=0 smart card in the MGTEK tool:

  // (image:https://example-code.com/images/gemalto_idprime_md_t0.JPG/endImage)

  // First let's load a private key into the Chilkat private key object.
  // (Chilkat provides the ability to load private keys from many different sources and formats.
  // this example loads from a PEM file.)
  final privKey = CkPrivateKey();
  try {
    privKey.loadPemFile('qa_data/rsa/rsaPrivKey_pkcs8.pem');
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  final scmd = CkScMinidriver();

  // First we need to acquire a context to the smart card in the reader where it is inserted.
  // Reader names (smart card readers or USB tokens) can be discovered
  // via List Readers or Find Smart Cards
  final readerName = 'Alcor Micro USB Smart Card Reader 0';
  try {
    scmd.acquireContext(readerName);
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  // If successful, the name of the currently inserted smart card is available:
  print('Card name: ${scmd.cardName}');

  // To import a private key, we'll need to be PIN authenticated.
  // For more details about smart card PIN authentication, see the Smart Card PIN Authentication Example
  final pinId = 'user';
  final retval = scmd.pinAuthenticate(pinId, '0000');
  if (retval != 0) {
    print('PIN Authentication failed.');
    scmd.deleteContext();
    return;
  }

  // Let's import into the "key exchange" position in key container #7.
  try {
    scmd.importKey(7, 'kex', privKey, 'user');
  } on ChilkatException {
    print('PIN Authentication failed.');
    scmd.deleteContext();
    return;
  }

  scmd.deleteContext();

  print('Success.');
