Demonstrates how to import a private key to the "signature" or "key exchange" location in the Nth key container on a smart card. Chilkat2 Perl

# 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.)
my $privKey = Chilkat2::PrivateKey->new;
my $success = $privKey->LoadPemFile('qa_data/rsa/rsaPrivKey_pkcs8.pem');
if (!$success) {
    print $privKey->LastErrorText, "\n";
    exit;
}

my $scmd = Chilkat2::ScMinidriver->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
my $readerName = 'Alcor Micro USB Smart Card Reader 0';
$success = $scmd->AcquireContext($readerName);
if (!$success) {
    print $scmd->LastErrorText, "\n";
    exit;
}

# If successful, the name of the currently inserted smart card is available:
print 'Card name: ', $scmd->CardName, "\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
my $pinId = 'user';
my $retval = $scmd->PinAuthenticate($pinId, '0000');
if ($retval != 0) {
    print "PIN Authentication failed.\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) {
    print "PIN Authentication failed.\n";
    $scmd->DeleteContext();
    exit;
}

$scmd->DeleteContext();

print "Success.\n";
