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 Java

import com.chilkatsoft.chilkat2.ChilkatException;
import com.chilkatsoft.chilkat2.Pkcs11;

public class ChilkatExample {

    public static void main(String[] args) {
        // 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 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.setSharedLibPath("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();
        } catch (ChilkatException e) {
            System.out.println(e.getLastErrorText());
            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;
        try {
            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 (ChilkatException e) {
            System.out.println(e.getLastErrorText());
            return;
        }

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