llSuccess = .F.

// 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("CkPkcs11")

// Set your shared lib path -- either a full path to the DLL, .so, or .dylib,
// or just the filename if the driver is in a location that can be automatically found. (Such as in C:\Windows\System32)
loPkcs11.SharedLibPath = "ShuttleCsp11_3003.dll"

// 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.  

llSuccess = loPkcs11.Initialize()
if (llSuccess = .F.) then
    ? loPkcs11.LastErrorText
    release loPkcs11
    return
endif

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

// Open a read/write session.
llReadWrite = .T.
llSuccess = loPkcs11.OpenSession(lnSlotID,llReadWrite)
if (llSuccess = .F.) then
    ? loPkcs11.LastErrorText
    release loPkcs11
    return
endif

// Do whatever is needed...
// ...
// ...

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

llSuccess = loPkcs11.CloseSession()
if (llSuccess = .F.) then
    ? loPkcs11.LastErrorText
    release loPkcs11
    return
