Improve part responsible for getting keys from removable media. Now it's done synchronously and it implies some issues. I'm gonna correct it to use udev soon. Next thing is give possibility to put keys inside initramfs. Later future is support for crypto related things which will get into my hands, since I'm just a student right now. :-) > >> I am also interested to see whether there are plans (or, indeed > >> attempted implementations) to introduce smartcard support to LUKS > >> partitions (boot or not)?

If you'd like to write support for smartcard, I'd be glad to see it as a separate module. Don't hesitate to post your progress on ml for our review. -- Amadeusz Żołnowski PGP key fpr: C700 CEDE 0C18 212E 49DA 4653 F013 4531 E1DB FAB5
