    // 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..
    // Here's the view of our Gemalto (Thales) IDPrime MD T=0 smart card in the MGTEK tool:

    

    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";
    var 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);

    // We likely shouldn't need to authenticate with the smart card (use a PIN) to simply get a public key,
    // so we can skip the PIN authenticatin step..

    // Let's get the key(s) present in Container #7.
    // In our case (shown in the image above), there is a private key in the "key exchange" position, but no key in the "signature" position.
    var pubkey_sig = new chilkat.PublicKey();
