# ------------------------------------------------------------------------
# The ExportPrivateKey method is deprecated:

# privatekeyObj is a CkPrivateKey

delete_CkPrivateKey $privatekeyObj

# ------------------------------------------------------------------------
# Do the equivalent using GetPrivateKey.
# Your application creates a new, empty PrivateKey object which is passed 
# in the last argument and filled upon success.
