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.

// Important: Don't forget to include the call to System.loadLibrary
// as shown at the bottom of this code sample.
package com.test;

import android.app.Activity;
import com.chilkatsoft.*;

import android.widget.TextView;
import android.os.Bundle;

public class SimpleActivity extends Activity {

  private static final String TAG = "Chilkat";

  // Called when the activity is first created.
  @Override
  public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    boolean 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.

    CkPkcs11 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");

    success = pkcs11.Initialize();
    if (success == false) {
        Log.i(TAG, pkcs11.lastErrorText());
        }
    else {
        Log.i(TAG, "PKCS11 successfully initialized.");
        }

      System.loadLibrary("chilkat");

      // Note: If the incorrect library name is passed to System.loadLibrary,
      // then you will see the following error message at application startup:
      //"The application <your-application-name> has stopped unexpectedly. Please try again."
