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.camel@pengutronix.de/

There's no code to implement this yet though.

Cheers,
Ahmad
