' 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.)
Dim privKey As Chilkat.PrivateKey
Set privKey = Chilkat.NewPrivateKey

success = privKey.LoadPemFile("qa_data/rsa/rsaPrivKey_pkcs8.pem")
If (success = False) Then
    Debug.Print privKey.LastErrorText
    Exit Sub
End If

Dim scmd As Chilkat.ScMinidriver
Set scmd = Chilkat.NewScMinidriver

' 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

readerName = "Alcor Micro USB Smart Card Reader 0"
success = scmd.AcquireContext(readerName)
If (success = False) Then
    Debug.Print scmd.LastErrorText
    Exit Sub
End If

' If successful, the name of the currently inserted smart card is available:
Debug.Print "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

pinId = "user"

retval = scmd.PinAuthenticate(pinId,"0000")
If (retval <> 0) Then
    Debug.Print "PIN Authentication failed."
    Dim success As Boolean
    success = scmd.DeleteContext()
    Exit Sub
End If

' Let's import into the "key exchange" position in key container #7.
success = scmd.ImportKey(7,"kex",privKey,"user")
If (success = False) Then
    Debug.Print "PIN Authentication failed."
    success = scmd.DeleteContext()
    Exit Sub
End If

success = scmd.DeleteContext()

Debug.Print "Success."
