    // This example requires the Chilkat API to have been previously unlocked.

    // Note: Chilkat's PKCS11 implementation runs on Windows, Linux, Mac OS X, and other supported operating systems.

    // or just the filename if the driver is in a location that can be automatically found. (Such as in C:\Windows\System32)

    // 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.

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