Being binary compatible with other implementations is not an objective for this patch set. If you need to migrate I'd suggest to get out a clear text password and side-load it into the trusted key framework. Jan and Mimi discussed this some weeks back: https://lore.kernel.org/linux-integrity/e8f149cddce55a4e4615396108e4c900cbec75a8.ca...@pengutronix.de/ There's no code to implement this yet though.
