(PowerBuilder) ScMinidriver - Delete Smart Card Key Container
Demonstrates how to delete the contents of a key container on a smart card (or USB token).
integer li_rc
oleobject loo_Scmd
string ls_ReaderName
integer li_Success
string ls_PinId
integer li_Retval
// 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.
loo_Scmd = create oleobject
// Use "Chilkat_9_5_0.ScMinidriver" for versions of Chilkat < 10.0.0
li_rc = loo_Scmd.ConnectToNewObject("Chilkat.ScMinidriver")
if li_rc < 0 then
destroy loo_Scmd
MessageBox("Error","Connecting to COM object failed")
return
end if
// 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
ls_ReaderName = "Alcor Micro USB Smart Card Reader 0"
li_Success = loo_Scmd.AcquireContext(ls_ReaderName)
if li_Success = 0 then
Write-Debug loo_Scmd.LastErrorText
destroy loo_Scmd
return
end if
// If successful, the name of the currently inserted smart card is available:
Write-Debug "Card name: " + loo_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
ls_PinId = "user"
li_Retval = loo_Scmd.PinAuthenticate(ls_PinId,"0000")
if li_Retval <> 0 then
Write-Debug "PIN Authentication failed."
loo_Scmd.DeleteContext()
destroy loo_Scmd
return
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.)
li_Success = loo_Scmd.DeleteKeyContainer(7)
if li_Success = 0 then
Write-Debug loo_Scmd.LastErrorText
loo_Scmd.DeleteContext()
destroy loo_Scmd
return
end if
loo_Scmd.DeleteContext()
Write-Debug "Successfully delete the contents of key container #7"
destroy loo_Scmd
