    //  This example requires the Chilkat API to have been previously unlocked.

    //  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.)
    var privKey = new chilkat.PrivateKey();

    var scmd = new chilkat.ScMinidriver();

    //  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
    var readerName = "Alcor Micro USB Smart Card Reader 0";
    success = scmd.AcquireContext(readerName);
    if (success == false) {
        console.log(scmd.LastErrorText);
        return;
    }

    //  If successful, the name of the currently inserted smart card is available:
    console.log("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
    var pinId = "user";
    var retval = scmd.PinAuthenticate(pinId,"0000");

    //  Let's import into the "key exchange" position in key container #7.
