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. Java

    // 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:

    // 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.)
    CkPrivateKey privKey = new CkPrivateKey();

    // If successful, the name of the currently inserted smart card is available:
    System.out.println("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
