(Node.js) ScMinidriver - Delete Smart Card Key Container

See more ScMinidriver Examples

Demonstrates how to delete the contents of a key container on a smart card (or USB token).

    // 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 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

    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

    // 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.)
