    //  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.

    var pkcs11 = new chilkat.Pkcs11();

    //  Use the PKCS11 driver (.dll, .so, .dylib) for your particular HSM.
    //  For example:
    pkcs11.SharedLibPath = "C:/Program Files (x86)/Gemalto/IDGo 800 PKCS#11/IDPrimePKCS11.dll";

    //  Use your HSM's PIN.
    var pin = "0000";

    //  Normal user = 1
    var userType = 1;

    //  Establish a logged-on user session with the HSM.

    //  Provide a template to find a PKCS11 object.
    var jsonTemplate = new chilkat.JsonObject();

    //  Find an RSA private key with the label "MySshKey".
    //  Here's an example of how the key was originally imported: 
    //  PKCS11 Import SSH Key
    jsonTemplate.UpdateString("class","private_key");
    jsonTemplate.UpdateString("key_type","rsa");
    jsonTemplate.UpdateString("label","MySshKey");

        console.log(pkcs11.LastErrorText);
        return;
    }

    //  The private key handle is only valid during the PKCS11 session.
    //  If you wish to use the private key in another PKCS11 session,
    //  you'll first need to find it.  See:  
    console.log("private key handle: " + privKeyHandle);

    //  Do whatever you wish with the private key handle...
    //  ...
