(PHP Extension) PKCS11 Find all Public Keys

See more PKCS11 Examples

Demonstrates how to list all public keys on an HSM.

Note: This example requires Chilkat v9.5.0.96 or later.

<?php

// The version number (9_5_0) should match version of the Chilkat extension used, omitting the micro-version number.
// For example, if using Chilkat v9.5.0.48, then include as shown here:
include("chilkat_9_5_0.php");

// 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 = new CkPkcs11();

// 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 needing to list public keys)
// Use your actual PIN here, or an empty string to skip login.

$userType = 1;
$success = $pkcs11->QuickSession($userType,$pin);
if ($success == false) {

// Note: To find public keys, we need a session, but it doesn't necessarily need to be logged-on.
