It needs a LOT of work. Ideally we should just call some shared function from reset(), and some other function from crypt_all() (and so on) and be done with it. On kernel side, things are much better. It's the host code that knocks me cold. > I am sending this offlist, as I do not want to pollute your thread IF > this is total PEBCAK No you didn't :-) But this is a good discussion here. magnum
