Honestly, I'm reluctant to add permanent sysfs uAPI just for temporary
debugging. Put it in debugfs.

There should be a tool suite that runs on top of this stuff and
presents a sensible user experiance, with man pages and so on.

Having to find/remember some baroque openssl command line with a
million options is not reasonable for a production kind of
environment.
