* 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.

loPkcs11 = CreateObject('Chilkat.Pkcs11')

* See PKCS11 Find Driver Library Path for information about how to find the 
* PKCS11 driver file (if not explicitly known) for the plugged-in token or smart card in reader.

* Pass -1 for the slotID to open a session on the first non-empty slot.
lnSlotID = -1

* Open a session.

    RELEASE loPkcs11

* Make it an authenticated session by calling Login.
* The smart card PIN is passed to the Login method.
* The user type can be one of three choices:
* 0 - Security Officer
* 1 - Normal User
* 2 - Context Specific.

    lnSuccess = loPkcs11.CloseSession()
    RELEASE loPkcs11
    CANCEL
ENDIF

* Change the PIN from 0000 to 1234
* This changes the PIN for the user type that is logged in.
lnSuccess = loPkcs11.SetPin(lcPin,"1234")
IF (lnSuccess = 0) THEN
    ? loPkcs11.LastErrorText
    lnSuccess = loPkcs11.CloseSession()
    RELEASE loPkcs11
    CANCEL
ENDIF

* Revert to an unauthenticated session by calling Logout.
lnSuccess = loPkcs11.Logout()
IF (lnSuccess = 0) THEN
    ? loPkcs11.LastErrorText
    lnSuccess = loPkcs11.CloseSession()
    RELEASE loPkcs11
    CANCEL
ENDIF

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