PKCS11 Sessions

See more PKCS11 Examples

Sample code showing how to open a PKCS11 session and then later close it.

Note: This example requires Chilkat v9.5.0.88 or later.

Chilkat2 PHP

<?php

use Chilkat2\Pkcs11;

// 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 Pkcs11();

// Set your shared lib path -- either a full path to the DLL, .so, or .dylib,
// or just the filename if the driver is in a location that can be automatically found. (Such as in C:\Windows\System32)
$pkcs11->SharedLibPath = 'ShuttleCsp11_3003.dll';

// Starting in Chilkat v9.5.0.96, there is a shorter way to establish
// a PKCS11 session with login.
// The QuickSession method was added in v9.5.0.96 and is the equivalent of
// calling Initialize, OpenSession, and Login.

try {
    $pkcs11->Initialize();

    // Pass -1 for the slotID to open a session on the first non-empty slot.
    $slotID = -1;

    // Open a read/write session.
    $readWrite = true;
    $pkcs11->OpenSession($slotID, $readWrite);

    // Do whatever is needed...
    // ...
    // ...

    // When finished, close the session.
    // It is important to close the session (memory leaks will occur if the session is not properly closed).

    $pkcs11->CloseSession();
} catch (\Chilkat2\Exception $e) {
    echo $e->getMessage(), "\n";
    exit;
}

echo "PKCS11 session successfully opened and closed.\n";
