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.

React Native

import { Pkcs11 } from '@chilkat/react-native'

function chilkatExample() {
  // 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.

  const pkcs11 = new Pkcs11();

  // 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.sharedLibPath = 'aetpkss1.dll';

  try {
    pkcs11.initialize();
    console.log('PKCS11 successfully initialized.');
  } catch {
    console.log(pkcs11.lastErrorText);
  }
}
