# 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 our Gemalto (Thales) IDPrime MD T=0 smart card in the MGTEK tool:



$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)

# We likely shouldn't need to authenticate with the smart card (use a PIN) to simply get a public key,
# so we can skip the PIN authenticatin step..

# Let's get the key(s) present in Container #7.
# In our case (shown in the image above), there is a private key in the "key exchange" position, but no key in the "signature" position.
$pubkey_sig = New-Object Chilkat.PublicKey
$pubkey_kex = New-Object Chilkat.PublicKey

$success = $scmd.GetContainerKeys(7,$pubkey_sig,$pubkey_kex)
if ($success -eq $false) {
    $($scmd.LastErrorText)
    exit
}

if ($pubkey_sig.Empty -eq $true) {
    $("No signature key is present.")
}
else {
    $("Signature key:")
    $($pubkey_sig.GetPem($true))
}

if ($pubkey_kex.Empty -eq $true) {
    $("No Key Exchange key is present.")
}
else {
    $("Key Exchange key:")
    $($pubkey_kex.GetPem($true))
}

$scmd.DeleteContext()

$("Success.")

# Here's the output of the above sample code:

# Card name: IDPrime MD T=0
# No signature key is present.
# Key Exchange key:
