==Key object handles==
The above crypto commands use key/crypto object handles. These handles can be either from IOSC_CreateObject(which can then be initialized with import_secret_key in the case of AES), or a built-in handle. The available built-in handles/keyids are listed below.

+
+The maximum number of keyobject-handles is 0x80, hence the highest valid keyobject-handle is 0x7F. Keyobject-handles <=0x40 are reserved for built-in handles, the rest are available for user-processes. Commands which write keyobjects' keydata are only allowed to use handles with value >0x40(user-process handles).
