ScMinidriver - Import Private Key to Smart Card

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

// 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 = new PrivateKey();
try {
    $privKey->LoadPemFile('qa_data/rsa/rsaPrivKey_pkcs8.pem');

    $scmd = new 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';
    $scmd->AcquireContext($readerName);
} catch (\Chilkat2\Exception $e) {
    echo $e->getMessage(), "\n";
    exit;
}

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

// Let's import into the "key exchange" position in key container #7.
try {
    $scmd->ImportKey(7, 'kex', $privKey, 'user');
} catch (\Chilkat2\Exception $e) {
    echo "PIN Authentication failed.\n";
    $scmd->DeleteContext();
    exit;
}

$scmd->DeleteContext();

echo "Success.\n";
