Hi, Apparently encrypted disks created with 2.4.21 are not readable by 2.6 and visa-versa. I'm using a patched 2.4.21 kernel with util-linux 2.11n (the rpms from freshmeat) and a 2.6.0-test2 with util-linux 2.12pre. Creating and reading an aes encrypted system (dd, losetup, mount) works fine with both systems, but it is not possible to read an encrypted file with an other system than the system it was created with. losetup works fine (it accepts a file of an other system), but mount doesn't work with "wrong fs type, bad option, bad superblock....." is if the password would be wrong. Is this in principle not working? Or I'm I doing something wrong? One thing is strange: losetup from 2.11n has the -k parameter, 2.12 doesnt have it and also doesn't ask so I don't know what key strength it is using. thanks ueli - Linux-crypto: cryptography in and on the Linux system Archive: http://mail.nl.linux.org/linux-crypto/
