With the default Redhat 6 installer, how can I choose the LUKS encryption?
Afaik if I prepare the disk like
cryptsetup luksFormat -c cast5-cbc-plain -s 128 /dev/$DEVICE
could be the "fastest" encryption, but the installer only prompts for password, then later, at the partitioning it recognizes it as "unknown" partition.
hello
I want use the encryption via LVM on my system.
I heard that the normal algo block mode that is used by the installer isn´t the best one.
Normally the installer uses: cryptsetup-cbc-essiv:sha256 (block mode)
I want to use: cryptsetup -c aes-xts-plain -s 512 luksFormat.
Is that possible with the 11.3 installation media?
thank you a lot!

It's been a while since last running any Ubuntu Linux disk encryption benchmarks, but thanks to recent encryption improvements within the upstream Linux ecosystem, it's time to deliver some new Linux disk encryption benchmarks.
I know some fragments of this question have been asked in previous posts and I have reviewed them - however I have a more thorough question...
I did not choose to do whole disk encryption when I used the alternative installer to install my 12.04 distro.
I setup a Fedora 18 VM tonight to test out the installer.
I would like to install Ubuntu 12.10 with two features:
partitioning of my disks (/ and /home should be separated, plus eventually a swap partition)
encryption of those said partitions
How should I do that in the Ubuntu 12.10 installer ? I know I should choose the option "Something else" at the step called "Allocate drive space". But what should I do after ?
I think I figured out where I went wrong. When I did cryptsetup on this disk I did a luksFormat on /dev/sdc1 instead of /dev/sdc. When I first got the device it was most likely partitioned as FAT32, so a /dev/sdc1 existed in the /dev directory. Is there a difference between luksFormat'ing /dev/sdc or /dev/sdc1 in that situation? I'm guessing yes.
Full disk encryption and LVM configuration in Ubuntu’s graphical installer showed that two very important features that were missing in Ubiquity, the installation program of Ubuntu Desktop, will finally be incorporated into the version that will ship in Ubuntu 12.10, which is due in late October.
That post was based on a test build version of Ubuntu 12.10, and at that time, the Advanced Partitioni
