No, you can NOT RELY ON HAVING THE KEY DATA. It might be in hardware.
You might have something which will perform sign/verify/encrypt/decrypt
operations *with* the key at your request, but which can never just
*give* you the key.

Any crypto API which relies on *having* the key is fundamentally wrong.
