The only code that we have right now that deals with keys at all is
the HWCryptoHook (CHIL) part, which is currently bound to nCipher
(they've implemented that library).  As it is now, the CHIL library
takes care of protecting the key, all the engine does is keep around
references to those keys and rely on the underlying library to protect
the keys at it sees fit.

All will actually depend on what the different vendor libraries will
do in this area.
