No. losetup still prompts for a Password.
I have just found out that life is easier with cryptsetup. But i have
to use an encrytion with little impact on performance. XOR would
by nice (I know it is unsave). How can i tell cryptsetup to use XOR.
Or is there another algorithm with a small performance impace?
Thanks in advance,
Harald
