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.

uses
    Winapi.Windows, Winapi.Messages, System.SysUtils, System.Variants, System.Classes, Vcl.Graphics,
    Vcl.Controls, Vcl.Forms, Vcl.Dialogs, Vcl.StdCtrls, Pkcs11;

success := False;

// 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 := CkPkcs11_Create();

// 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.
CkPkcs11_putSharedLibPath(pkcs11,'aetpkss1.dll');
