ScMinidriver - Import Private Key to Smart Card

See more ScMinidriver Examples

Demonstrates how to import a private key to the "signature" or "key exchange" location in the Nth key container on a smart card. VBScript

Dim fso, outFile
Set fso = CreateObject("Scripting.FileSystemObject")
'Create a Unicode (utf-16) output text file.
Set outFile = fso.CreateTextFile("output.txt", True, True)

success = 0

'  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.)
set privKey = CreateObject("Chilkat.PrivateKey")
success = privKey.LoadPemFile("qa_data/rsa/rsaPrivKey_pkcs8.pem")
If (success = 0) Then
    outFile.WriteLine(privKey.LastErrorText)
    WScript.Quit
End If

set scmd = 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
    outFile.WriteLine(scmd.LastErrorText)
    WScript.Quit
End If

'  If successful, the name of the currently inserted smart card is available:
outFile.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
pinId = "user"
retval = scmd.PinAuthenticate(pinId,"0000")
If (retval <> 0) Then
    outFile.WriteLine("PIN Authentication failed.")
    success = scmd.DeleteContext()
    WScript.Quit
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
    outFile.WriteLine("PIN Authentication failed.")
    success = scmd.DeleteContext()
    WScript.Quit
End If

success = scmd.DeleteContext()

outFile.WriteLine("Success.")
