hi,
i've read a couple of manuals about encrypting a harddrive with crypto luks and i'm a bit confused. well, cryptoluks supports aes-256 - 256bit max keys. i've found though in few places that somebody used 2048bit key or 3072but key. is the algorithm using all those bits or just truncates it to 256 bit key? i've succesfully added a 3072bit key to the partition but have no clue how to find out if it's using only 256bit or whole 3072bits. thanks in advance for help
