# 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.



$scmd = New-Object 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 -eq $false) {
    $($scmd.LastErrorText)
    exit
}

# If successful, the name of the currently inserted smart card is available:
$("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
$pinId = "user"
$retval = $scmd.PinAuthenticate($pinId,"0000")
if ($retval -ne 0) {
    $("PIN Authentication failed.")
    $scmd.DeleteContext()
    exit
}

# 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 -eq $false) {
    $($scmd.LastErrorText)
    $scmd.DeleteContext()
    exit
}

$scmd.DeleteContext()
$("Successfully delete the contents of key container #7")
