ScMinidriver - Import Private Key to Smart Card

See more ScMinidriver Examples

Demonstrates how to import a private key to the "signature" or "key exchange" location in the Nth key container on a smart card. 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 before importing a private key.
# Here's the view of our Gemalto (Thales) IDPrime MD T=0 smart card in the MGTEK tool:

# (image:https://example-code.com/images/gemalto_idprime_md_t0.JPG/endImage)

# 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 = chilkat::CkPrivateKey->new();
$success = $privKey->LoadPemFile("qa_data/rsa/rsaPrivKey_pkcs8.pem");
if ($success == 0) {
    print $privKey->lastErrorText() . "\r\n";
    exit;
}

$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 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) {
    print "PIN Authentication failed." . "\r\n";
    $scmd->DeleteContext();
    exit;
}

# Let's import into the "key exchange" position in key container #7.
$success = $scmd->ImportKey(7,"kex",$privKey,"user");
if ($success == 0) {
    print "PIN Authentication failed." . "\r\n";
    $scmd->DeleteContext();
    exit;
}

$scmd->DeleteContext();

print "Success." . "\r\n";
