       With this function, the caller sets the key for subsequent hashing operations. This call is applicable
       for keyed message digests.

       After the caller provided the key, the caller may securely destroy the key as it is now maintained by the
       kernel.

       return 0 upon success; a negative errno-style error code if an error occurred
