Demonstrates how to delete the contents of a key container on a smart card (or USB token). 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..
// Here's the view of the card we happen to be using: a Gemalto (Thales) IDPrime MD T=0 smart card.

// 

$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';
try {
    $scmd->AcquireContext($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 delete the contents of a key container, 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 delete the contents of key container #7
// This deletes both keys (signature key and "key exchange" key) that might be present in the key container.
// (It is not possible to delete just one or the other.)
try {
    $scmd->DeleteKeyContainer(7);
