It seems like entirely the wrong thing to do to me. First consider that the users you are talking about do not have backups. Hence their data must be basically worthless anyways! Second, their data is so little in need of protection that something as simple and as a backup already makes them do without encryption. Hence their data must actually not be sensitive in any way! Given these two things, why on earth do you want these people to use encryption? Security comes at a price. That price has to be paid. No price - no security. There is _no_ way to fix this and trying to do so only does damage to the user by making things too complex for them to handle. Regards, Arno -- Arno Wagner, Dr. sc. techn., Dipl.
