Hi!

Maybe thats too simple, but why not just overwrite the keys in DRAM as
soon as a shutdown is signaled? Should be quickly patched and work fine
except for a sudden power down. Well, "as soon as possible" might be a
bit rush tho, when the filesystem unmounting still needs the keys but
I'm sure there is a way to do this right.

Regards,
Andreas
