I came accross a little guide on how to encrypt a whole disk drive with a steganographic system (dm-crypt / LUKS) and I thought I could try it as *buntu and debian are so close to each other...
The URL is http://www.saout.de/tikiwiki/tiki-in...eviceUsingLUKS
Well, I started with it... skipped Step 2 (as I have no clue so far on how to do that) and now I fail at Step 6. I get following error notice:
hyper@xubi:/dev$ sudo cryptsetup --verbose --verify-passphrase luksFormat /dev/hda1
This will overwrite data on /dev/hda1 irrevocably.
Are you sure? (Type uppercase yes): YES
Enter LUKS passphrase:
Failed to setup dm-crypt key mapping.
Check kernel for support for the aes-cbc-essiv:sha256 cipher spec and verify that /dev/hda1 contains at least 133 sectors.
Failed to write to key storage.
So I guess that the (X)ubuntu Feisty 2.6.20-14-generic kernel doesn't have one of the options enabled that is being talked about in Step 2 of the howto.
So my questions are:
(1) Am I right with my assumption from that error notice?
and if so (2) how to I enable those options?
