ScMinidriver - Delete Smart Card Key Container

See more ScMinidriver Examples

Demonstrates how to delete the contents of a key container on a smart card (or USB token). Perl

use chilkat();

$success = 0;

# 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 = chilkat::CkScMinidriver->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
$readerName = "Alcor Micro USB Smart Card Reader 0";
$success = $scmd->AcquireContext($readerName);
if ($success == 0) {
    print $scmd->lastErrorText() . "\r\n";
    exit;
}

# If successful, the name of the currently inserted smart card is available:
print "Card name: " . $scmd->cardName() . "\r\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." . "\r\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() . "\r\n";
    $scmd->DeleteContext();
    exit;
}

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