# 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.)
$privKey = New-Object Chilkat.PrivateKey
$success = $privKey.LoadPemFile("qa_data/rsa/rsaPrivKey_pkcs8.pem")
if ($success -eq $false) {
    $($privKey.LastErrorText)
    exit
}

$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 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 -ne 0) {
    $("PIN Authentication failed.")
    $scmd.DeleteContext()
    exit
}

# Let's import into the "key exchange" position in key container #7.
$success = $scmd.ImportKey(7,"kex",$privKey,"user")
if ($success -eq $false) {
    $("PIN Authentication failed.")
    $scmd.DeleteContext()
    exit
}

$scmd.DeleteContext()

$("Success.")
