' 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")

' Get the handle of the public key we wish to export.
' You can find public keys in many different ways.
' This example will search for a public key by label.
