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. .NET Core C#

bool success = false;

// 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:

// (image:https://example-code.com/images/gemalto_idprime_md_t0.JPG/endImage)

// 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.)
Chilkat.PrivateKey privKey = new Chilkat.PrivateKey();
success = privKey.LoadPemFile("qa_data/rsa/rsaPrivKey_pkcs8.pem");
if (success == false) {
    Debug.WriteLine(privKey.LastErrorText);
    return;
}

Chilkat.ScMinidriver 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
string readerName = "Alcor Micro USB Smart Card Reader 0";
success = scmd.AcquireContext(readerName);
if (success == false) {
    Debug.WriteLine(scmd.LastErrorText);
    return;
}

// If successful, the name of the currently inserted smart card is available:
Debug.WriteLine("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
string pinId = "user";
int retval = scmd.PinAuthenticate(pinId,"0000");
if (retval != 0) {
    Debug.WriteLine("PIN Authentication failed.");
    scmd.DeleteContext();
    return;
}

// Let's import into the "key exchange" position in key container #7.
success = scmd.ImportKey(7,"kex",privKey,"user");
if (success == false) {
    Debug.WriteLine("PIN Authentication failed.");
    scmd.DeleteContext();
    return;
}

scmd.DeleteContext();

Debug.WriteLine("Success.");
