(C#) ScMinidriver - Import Private Key to Smart CardSee more ScMinidriver ExamplesDemonstrates how to import a private key to the "signature" or "key exchange" location in the Nth key container on a smart card.
// 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.) Chilkat.PrivateKey privKey = new Chilkat.PrivateKey(); bool 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."); // Here's the MGTEK view of the smart card after importing the private key: |
