// 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.

// (image:https://example-code.com/images/gemalto_idprime_after_key_import.JPG/endImage)

$scmd = new CkScMinidriver();

// 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 == false) {
    print $scmd->lastErrorText() . "\n";
    exit;
}

// If successful, the name of the currently inserted smart card is available:
print '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) {
    print '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.)
$success = $scmd->DeleteKeyContainer(7);

    print $scmd->lastErrorText() . "\n";
