Perl Requires Chilkat v11.0.0+

PKCS11 Export Public Key from HSM

See more PKCS11 Examples

Demonstrates how to export a public key from a smartcard or token. Perl

use chilkat();

$success = 0;

#  This example requires the Chilkat API to have been previously unlocked.
#  See Global Unlock Sample for sample code.

#  Note: Chilkat's PKCS11 implementation runs on Windows, Linux, Mac OS X, and other supported operating systems.

$pkcs11 = chilkat::CkPkcs11->new();

#  Use the PKCS11 driver (.dll, .so, .dylib) for your particular HSM.
#  (The format of the path will change with the operating system.  Obviously, "C:/" is not used on non-Windows systems.
$pkcs11->put_SharedLibPath("C:/Program Files (x86)/Gemalto/IDGo 800 PKCS#11/IDPrimePKCS1164.dll");

#  Establish a logged-on session. (We can typically skip the login by passing an empty PIN if only working with public keys)
#  Use your actual PIN here, or an empty string to skip login.
$pin = "0000";
$userType = 1;
$success = $pkcs11->QuickSession($userType,$pin);
if ($success == 0) {
    print $pkcs11->lastErrorText() . "\r\n";
    exit;
}

#  Get the handle of the public key we wish to export.
#  You can find public keys in many different ways.
#  This example will search for a public key by label.

#  Provide a template to find a PKCS11 object.
$jsonTemplate = chilkat::CkJsonObject->new();

#  Find the public key with the label "Belgium eHealth".
$jsonTemplate->UpdateString("class","public_key");
$jsonTemplate->UpdateString("label","Belgium eHealth");

$pubKeyHandle = $pkcs11->FindObject($jsonTemplate);
if ($pubKeyHandle == 0) {
    print $pkcs11->lastErrorText() . "\r\n";
    exit;
}

#  Export to a Chilkat public key object.
$pubKey = chilkat::CkPublicKey->new();
$success = $pkcs11->ExportPublicKey($pubKeyHandle,$pubKey);
if ($success == 0) {
    print $pkcs11->lastErrorText() . "\r\n";
    exit;
}

#  Get the public key as PKCS8 PEM.
print $pubKey->getPem(0) . "\r\n";

$pkcs11->Logout();
$pkcs11->CloseSession();
