This section defines the object class CKO_HW_FEATURE for type CK_OBJECT_CLASS as used in the CKA_CLASS attribute of objects.
Hardware feature objects (CKO_HW_FEATURE) represent features of the device. They provide an easily expandable method for introducing new value-based features to the cryptoki interface.
When searching for objects using C_FindObjectsInit and C_FindObjects, hardware feature objects are not returned unless the CKA_CLASS attribute in the template has the value CKO_HW_FEATURE. This protects applications written to previous versions of cryptoki from finding objects that they do not understand.
