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.

    std::cout << "Card name: " << scmd.cardName() << "\r\n";

    // 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
