I moved from Ubuntu for the sake of simplicity in order to have my disk encrypted. Later it just hit me I checked Encrypted for the drive. I had no idea how. I found out in the Fedora docs that was AES128 and SHA256. And I assume a change would mean backup the whole system, choose another, say Twofish, than restore the system. But how can I tune it for the future? Is there a GUI? Had I missed something in the installer where I could have chosen among the dm-crypt options?
And second how do I do to make a portable storage on some USB flash drive? How do I make it both fully encrypted and as easy to use as my system: just push the flash in and be just asked for a passphrase? I'm trying to move from TrueCrypt as I see it's not very liked over here. But I would like some automation, or at least a GUI.
