(Visual Basic 6.0) ScMinidriver - Delete Smart Card Key Container

See more ScMinidriver Examples

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

Chilkat ActiveX Downloads

ActiveX for 32-bit and 64-bit Windows

' 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.



Dim scmd As New ChilkatScMinidriver

' 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
Dim readerName As String
readerName = "Alcor Micro USB Smart Card Reader 0"
Dim success As Long
success = scmd.AcquireContext(readerName)
If (success = 0) 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 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
Dim pinId As String
pinId = "user"
Dim retval As Long
retval = scmd.PinAuthenticate(pinId,"0000")
If (retval <> 0) Then
    Debug.Print "PIN Authentication failed."
    success = scmd.DeleteContext()
    Exit Sub
End If

' 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.)
success = scmd.DeleteKeyContainer(7)
If (success = 0) Then
    Debug.Print scmd.LastErrorText
    success = scmd.DeleteContext()
    Exit Sub
End If

success = scmd.DeleteContext()
Debug.Print "Successfully delete the contents of key container #7"
