Demonstrates how to delete the contents of a key container on a smart card (or USB token). AutoIt

Local $bSuccess = False

;  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..
;  Here's the view of the card we happen to be using: a Gemalto (Thales) IDPrime MD T=0 smart card.

;  (image:https://example-code.com/images/gemalto_idprime_after_key_import.JPG/endImage)

$oScmd = ObjCreate("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
Local $sReaderName = "Alcor Micro USB Smart Card Reader 0"
$bSuccess = $oScmd.AcquireContext($sReaderName)
If ($bSuccess = False) Then
    ConsoleWrite($oScmd.LastErrorText & @CRLF)
    Exit
EndIf

;  If successful, the name of the currently inserted smart card is available:
ConsoleWrite("Card name: " & $oScmd.CardName & @CRLF)

;  To delete the contents of a key container, we'll need to be PIN authenticated..

;  For more details about smart card PIN authentication, see the Smart Card PIN Authentication Example
Local $sPinId = "user"
Local $iRetval = $oScmd.PinAuthenticate($sPinId,"0000")
If ($iRetval <> 0) Then
    ConsoleWrite("PIN Authentication failed." & @CRLF)
    $oScmd.DeleteContext()
    Exit
EndIf

;  Let's delete the contents of key container #7
;  This deletes both keys (signature key and "key exchange" key) that might be present in the key container.
;  (It is not possible to delete just one or the other.)
$bSuccess = $oScmd.DeleteKeyContainer(7)
If ($bSuccess = False) Then
    ConsoleWrite($oScmd.LastErrorText & @CRLF)
    $oScmd.DeleteContext()
    Exit
EndIf

$oScmd.DeleteContext()
ConsoleWrite("Successfully delete the contents of key container #7" & @CRLF)
