(PHP Extension) PKCS11 Initialize

See more PKCS11 Examples

The first thing to do to interact with a smart card or USB security token using PKCS11 is to call Initialize. It loads the vendors DLL/shared library and initializes the Cryptoki library. (The Cryptoki library is the DLL/shared lib provided by the smart card vendor.)

Note: This example requires Chilkat v9.5.0.88 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();

// You'll need to know in advance the name and possibly the full path to the smart card vendor's shared library.
// On Windows systems it is a .dll.   On Linux it is a .so.  On Mac OS X it will be a .dylib.
// On Windows, if you set the SharedLibPath equal to just the name of the DLL, then it is assumed to be located in the Windows system directory
// which contains dynamic-link libraries and drivers. The Windows system directory is typically C:\Windows\System32

// In this example we will pass just the name of the DLL because it is located in C:\Windows\System32.
// On non-Windows systems you should specify the full path to the shared lib.
// Also use the full path on Windows systems where the smart card vendor's DLL does not install to C:\Windows\System32.
$pkcs11->put_SharedLibPath('aetpkss1.dll');
