// 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 the card we happen to be using: a Gemalto (Thales) IDPrime MD T=0 smart card.



var scmd = new 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
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 delete the contents of a key container, 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");
if (retval !== 0) {
    console.log("PIN Authentication failed.");
    scmd.DeleteContext();
    return;
}

// Let's delete the contents of key container #7
// This deletes both keys (signature key and "key exchange" key) that might be present in the key container.
// (It is not possible to delete just one or the other.)
success = scmd.DeleteKeyContainer(7);

    console.log(scmd.LastErrorText);
    scmd.DeleteContext();
