//  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 COM("Chilkat.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';
$success = $scmd->AcquireContext($readerName);
if ($success == 0) {
    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 = $scmd->DeleteKeyContainer(7);
if ($success == 0) {
    print $scmd->LastErrorText . "\n";
    $scmd->DeleteContext();
    exit;
}

$scmd->DeleteContext();
print 'Successfully delete the contents of key container #7' . "\n";
