ScMinidriver - Import a Certificate to IDPrime MD T=0 Smart Card

See more ScMinidriver Examples

Demonstrates how to import a certificate and its private key to a key container on an ID Prime MD T=0 smartcard.

Note: Requires Chilkat v9.5.0.88 or later. This example only runs on Windows because ScMinidriver is a Windows-only class.

.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.ScMinidriver scmd = new Chilkat.ScMinidriver();

// Reader names (smart card readers or USB tokens) can be discovered
// via List Readers or Find Smart Cards
string readerName = "SCM Microsystems Inc. SCR33x 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);

// The IDPRime MD smart card has 4 different PIN roles:
// "user" -- Primary Card PIN
// "admin" -- Administrator PIN
// "3" -- Digital Signature PIN
// "4" -- Unblock only PIN (PUK)
// To import a certificate to the "IDPrime MD T=0" smart card, we must first PIN authenticate using "user", and then also PIN authenticate using "3" (the Digital Signature PIN)
string pinId = "user";
// (Of course, use your PIN which may be different than "0000")
int retval = scmd.PinAuthenticate(pinId,"0000");
if (retval != 0) {
    Debug.WriteLine("PIN Authentication failed.");
    scmd.DeleteContext();
    return;
}

Chilkat.Cert cert = new Chilkat.Cert();

// Load the cert + private key from a .p12/.pfx
// We got this .p12 from https://badssl.com/download/
string password = "badssl.com";
success = cert.LoadPfxFile("qa_data/pfx/badssl.com-client.p12",password);
if (success == false) {
    Debug.WriteLine(cert.LastErrorText);
    scmd.DeleteContext();
    return;
}

// Also authenticate using "3", the digital signature PIN.
// (Of course, use your PIN which may be different than "12345678")
retval = scmd.PinAuthenticate("3","12345678");
if (retval != 0) {
    Debug.WriteLine("PIN Authentication failed.");
    scmd.DeleteContext();
    return;
}

// Let's import this certificate as the "signature" key/cert in key container #6.
int containerIndex = 6;
string keySpec = "sig";
// Note the last argument (the pin ID) is "3".  This is the required PIN ID for the IDPrime MD T=0 smart card.
success = scmd.ImportCert(cert,containerIndex,keySpec,"3");
if (success == false) {
    Debug.WriteLine(scmd.LastErrorText);
}

    Debug.WriteLine("Successfully imported the cert + private key onto the smart card.");
}

// Delete the context when finished with the card.
