Well again whether that should be done is up to the dm-crypt maintainers. > seprate interface to grab a block cipher _or_ a stream cipher. So Just because something isn't a stream cipher doesn't mean that it is safe for disk encryption. People simply shouldn't be using random algorithms for disk encryption. > I can't imaging how you want to fix arc4 that it will work in dm-crypt. I thought I've explained this before.
