PKCS11 Sessions

Sample code showing how to open a PKCS11 session and then later close it.

Note: This example requires Chilkat v9.5.0.88 or later.

LOCAL oPkcs11

//  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.

oPkcs11 := CreateObject("Chilkat.Pkcs11")

//  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)
oPkcs11: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.  

nSuccess := oPkcs11:Initialize()
IF (nSuccess == 0)
    ? oPkcs11:LastErrorText
    oPkcs11:destroy()
    RETURN
ENDIF

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

//  Open a read/write session.
nReadWrite := 1
nSuccess := oPkcs11:OpenSession(nSlotID, nReadWrite)
IF (nSuccess == 0)
    ? oPkcs11:LastErrorText
    oPkcs11:destroy()
    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).

nSuccess := oPkcs11:CloseSession()
IF (nSuccess == 0)
    ? oPkcs11:LastErrorText
    oPkcs11:destroy()
    RETURN
