'  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.)
set privKey = Server.CreateObject("Chilkat.PrivateKey")
success = privKey.LoadPemFile("qa_data/rsa/rsaPrivKey_pkcs8.pem")
If (success = 0) Then
    Response.Write "<pre>" & Server.HTMLEncode( privKey.LastErrorText) & "</pre>"
    Response.End
End If

set scmd = Server.CreateObject("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
readerName = "Alcor Micro USB Smart Card Reader 0"
success = scmd.AcquireContext(readerName)
If (success = 0) Then
    Response.Write "<pre>" & Server.HTMLEncode( scmd.LastErrorText) & "</pre>"
    Response.End
End If

'  If successful, the name of the currently inserted smart card is available:
Response.Write "<pre>" & Server.HTMLEncode( "Card name: " & scmd.CardName) & "</pre>"

'  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
    Response.Write "<pre>" & Server.HTMLEncode( "PIN Authentication failed.") & "</pre>"
    success = scmd.DeleteContext()
    Response.End
End If

'  Let's import into the "key exchange" position in key container #7.
success = scmd.ImportKey(7,"kex",privKey,"user")
If (success = 0) Then
    Response.Write "<pre>" & Server.HTMLEncode( "PIN Authentication failed.") & "</pre>"
    success = scmd.DeleteContext()
    Response.End
End If
