#  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 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 = chilkat::CkPrivateKey->new();
$success = $privKey->LoadPemFile("qa_data/rsa/rsaPrivKey_pkcs8.pem");
if ($success == 0) {
    print $privKey->lastErrorText() . "\r\n";
    exit;
}

$scmd = chilkat::CkScMinidriver->new();

#  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 == 0) {
    print $scmd->lastErrorText() . "\r\n";
    exit;
}

#  If successful, the name of the currently inserted smart card is available:
print "Card name: " . $scmd->cardName() . "\r\n";

#  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 != 0) {
    print "PIN Authentication failed." . "\r\n";
    $scmd->DeleteContext();
    exit;
}

#  Let's import into the "key exchange" position in key container #7.
$success = $scmd->ImportKey(7,"kex",$privKey,"user");
if ($success == 0) {
    print "PIN Authentication failed." . "\r\n";
    $scmd->DeleteContext();
    exit;
