How to access encrypted volumes from live CDs

Sun, 25 Jan 2009 00:00:00 +0000

Once you have decided to encrypt your hard drive, you might find yourself in the situation where you need to pull off data from it when the regular decryption mechanisms you use are not in place. E.g. when the OS is not booting or the drive has some physical problems. In that case you need to boot from a CD/DVD that supports the encryption technology that you used. In my case I need a live Ubuntu CD/DVD, preferably the same version that was used to encrypt the disk! Otherwise there might be incompatibilities:sudo apt-get install lvm2 cryptsetupsudo modprobe dm-cryptsudo cryptsetup luksOpen /dev/sda2 crypt1 (result: key slot0 unlocked, command successful)sudo vgscan --mknodes (result: Found volume group "default")sudo vgchange -ay (logical volumes become active)sudo mkdir /volume1, etc.sudo mount /dev/default/root1 /volume1

Mouting of encrypted partitions under SuSE 9.3 (losetup, cryptotab, twofish256, twofishSL92)

I have one encrypted partition that was created under SuSE 9.2. After a fresh install of 9.3 (not an update) the mounting of that partition during bootup failed. I could, however, still mount it manually later using another loopdevice. To fix this, I had to change the encryption algorithm in /etc/cryptotab from twofish256 to twofishSL92.
