// 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.

// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.Pkcs11')
$pkcs11 = new COM("Chilkat.Pkcs11");

// 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->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 . "\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.
// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.JsonObject')
$jsonTemplate = new COM("Chilkat.JsonObject");

// 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 . "\n";
    exit;
}

// Export to a Chilkat public key object.
// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.PublicKey')
$pubKey = new COM("Chilkat.PublicKey");
$success = $pkcs11->ExportPublicKey($pubKeyHandle,$pubKey);
if ($success == 0) {
