Ok cool, thanks for the quick response. i am compiling cryptsetup, so can i am guessing i will be able to call libcryptsetup API.
It was quicker to implement it than explain:) Try upstream git now, see this commit http://code.google.com/p/cryptsetup/source/detail?r=d54204564519682881e9a125dd37e3c39502ebfa# Basically, if you have volume key somewhere in file, you can not only use it to format cryptsetup luksFormat --master-key-file <vk_file> <device> but you can also open device using it now cryptsetup luksOpen --master-key-file <vk_file> <device> <mapped_name> Obviously, you are responsible that VK is generated properly (enough entropy etc) and that you store VK file safely (anyone can map device using this file without passphrase knowledge). Use at your own risk :-) (I will release 1.4.2 version perhaps soon.)
