Huh? You can't use full-disk encryption on a Linux installation? Are you absolutely positive about that, because... I don't believe that everyone I've seen say is using full-disk encryption was booting Windows?AES is fine -- any variant above AES-128 probably is too. Don't go trusting your life to that information or anything though; AES is really a family of algorithms, and to my knowledge none are totally broken. AES-128 is getting pretty close to broken though I think.Sero: I mean no offense, I truly don't, but if you're having difficulty finding the iso you downloaded... I really don't recommend trying to use Linux as a primary OS even just for SR. We all have to learn sometime, there's nothing wrong with that, but if you're at the stage where finding the iso you downloaded is a problem, you're going to lose your mind wrestling with Linux. It sounds to me like you downloaded a tarball or something and not the iso, for what it's worth. An iso is a disc image file, I'm not sure why they'd distribute it along with the Linux equivalent of a zip file -- it wastes bandwidth when people only need one or the other, not both.
