* 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.

* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.Pkcs11')
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.

* We haven't logged in, but we can set the Normal User's PIN directly by providing 
* the existing PIN, and the new PIN.

* Change the PIN from 1234 to 0000
lnSuccess = loPkcs11.SetPin("1234","0000")
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).
