// 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.

Dim pkcs11 As New 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)
pkcs11.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.  

Dim success As Boolean
success = pkcs11.Initialize()
If (success = False) Then
    System.DebugLog(pkcs11.LastErrorText)
    Return
End If

// Pass -1 for the slotID to open a session on the first non-empty slot.
Dim slotID As Int32
slotID = -1

// Open a read/write session.
Dim readWrite As Boolean
readWrite = True
success = pkcs11.OpenSession(slotID,readWrite)
If (success = False) Then
    System.DebugLog(pkcs11.LastErrorText)
    Return
End If

// 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).

success = pkcs11.CloseSession()
If (success = False) Then
    System.DebugLog(pkcs11.LastErrorText)
    Return
End If

System.DebugLog("PKCS11 session successfully opened and closed.")
