    // Starting in Chilkat v9.5.0.96, there is a shorter way to establish
    // a PKCS11 session with login.

    // calling Initialize, OpenSession, and Login.

    // ...

    // When finished, close the session.
    // It is important to close the session (memory leaks will occur if the session is not properly closed).
