// 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.)
loPrivKey = createobject("CkPrivateKey")
llSuccess = loPrivKey.LoadPemFile("qa_data/rsa/rsaPrivKey_pkcs8.pem")
if (llSuccess = .F.) then
    ? loPrivKey.LastErrorText
    release loPrivKey
    return
endif

loScmd = createobject("CkScMinidriver")

// 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
lcReaderName = "Alcor Micro USB Smart Card Reader 0"
llSuccess = loScmd.AcquireContext(lcReaderName)
if (llSuccess = .F.) then
    ? loScmd.LastErrorText
    release loPrivKey
    release loScmd
    return
endif

// If successful, the name of the currently inserted smart card is available:
? "Card name: " + loScmd.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
lcPinId = "user"
lnRetval = loScmd.PinAuthenticate(lcPinId,"0000")
if (lnRetval <> 0) then
    ? "PIN Authentication failed."
    loScmd.DeleteContext()
    release loPrivKey
    release loScmd
    return
endif

// Let's import into the "key exchange" position in key container #7.
llSuccess = loScmd.ImportKey(7,"kex",loPrivKey,"user")
if (llSuccess = .F.) then
    ? "PIN Authentication failed."
    loScmd.DeleteContext()
    release loPrivKey
    release loScmd
    return
endif

loScmd.DeleteContext()

? "Success."

// Here's the MGTEK view of the smart card after importing the private key:
