I don't really understand what I should get from this. It lacks motivation and function of this structure, even the name of the structure. Hardware bound key does not mean anything at all without a context.

Undocumented. 2. No idea why you want to use a macro instead of inline function. BR, Jarkko

Hardware bound keys buffer has additional information, that will be accessed using this new structure. structure members are: - flags, flags for hardware specific information. - key_sz, size of the plain key.
