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

Use ChilkatAx-win32.pkg

Procedure Test
    Boolean iSuccess
    Handle hoPkcs11
    Integer iSlotID
    Boolean iReadWrite
    String sTemp1

    Move False To iSuccess

    // 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.

    Get Create (RefClass(cComChilkatPkcs11)) To hoPkcs11
    If (Not(IsComObjectCreated(hoPkcs11))) Begin
        Send CreateComObject of hoPkcs11
    End

    // 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)
    Set ComSharedLibPath Of hoPkcs11 To "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.  

    Get ComInitialize Of hoPkcs11 To iSuccess
    If (iSuccess = False) Begin
        Get ComLastErrorText Of hoPkcs11 To sTemp1
        Showln sTemp1
        Procedure_Return
    End

    // Pass -1 for the slotID to open a session on the first non-empty slot.
    Move -1 To iSlotID

    // Open a read/write session.
    Move True To iReadWrite
    Get ComOpenSession Of hoPkcs11 iSlotID iReadWrite To iSuccess
    If (iSuccess = False) Begin
        Get ComLastErrorText Of hoPkcs11 To sTemp1
        Showln sTemp1
        Procedure_Return
    End

    // 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).

    Get ComCloseSession Of hoPkcs11 To iSuccess
    If (iSuccess = False) Begin
        Get ComLastErrorText Of hoPkcs11 To sTemp1
        Showln sTemp1
        Procedure_Return
    End

    Showln "PKCS11 session successfully opened and closed."
