I've rewritten my example request-key program to get a key holding the
real key creation program from a key in the user's session key, so that, say,
a desktop such as KDE could supply a GUI front end.

http://people.redhat.com/~dhowells/keys/request-key.c
http://people.redhat.com/~dhowells/keys/request-key-dhowells.sh

So as me, I can do:

keyctl add user request-key:create /tmp/request-key-dhowells.sh @s

And then:

keyctl request user metal:copper

And the request-key program will change to my UID/GID, look around for the a
key telling it which program to run, and then run my default script.
