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.

Java

import com.chilkatsoft.*;

public class ChilkatExample {

  static {
    try {
        System.loadLibrary("chilkat");
    } catch (UnsatisfiedLinkError e) {
      System.err.println("Native code library failed to load.\n" + e);
      System.exit(1);
    }
  }

  public static void main(String argv[])
  {
    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();

    // 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.put_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.  

    success = pkcs11.Initialize();
    if (success == false) {
        System.out.println(pkcs11.lastErrorText());
        return;
        }

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

    // Open a read/write session.
    boolean readWrite = true;
    success = pkcs11.OpenSession(slotID,readWrite);
    if (success == false) {
        System.out.println(pkcs11.lastErrorText());
        return;
        }

    // 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).

    success = pkcs11.CloseSession();
    if (success == false) {
        System.out.println(pkcs11.lastErrorText());
        return;
        }

    System.out.println("PKCS11 session successfully opened and closed.");
  }
