Is there a whole disk encryption software for Linux?
 
I am planning to install Linux on my laptop, but I am not comfortable of running my laptop without a disk encryption software such as PC Guardians. currently i am using CompuSec, but it won't work in Linux.

In case you wonder what i have on my disk, mostly me and gf and stuff. *smile.

Have a look at [1]. Works like a charm. Some distributions even bring along their own means of disk encryption.

If you need a portable encryption that you can use both in Linux and in Windows you should have a look at [2].

The last July Issue of Linux Gazette had two articles on encryption. I think it would be better to just encrypt your /home partition.

If your kernel supports it, I had to recompile my own, you can use AES-loop encryption. I haven't used the other forms of encryption so I couldn't say how well they work, but I made a script for my live cd that would encrypt the swap, root and home partitions and create an decryption boot disc.

AES-loop encryption seemed to run quite well and I couldn't notice any real performance issuies with it

Or dm-crypt and it looks like there is a software for reading it from windows but haven't tried it.
I'm using dm-crypt since maybe 2 years, never had a problem. Half of my disk is encrypted, all my personnal datas go there. Performance can be an issue but I haven't really benchmarked it.

Disk encryption software
 
Does anybody know a disk encryption software that I can use in both Linux and Windows?

The TrueCrypt does not work because it does not encrypt a whole disk or the boot partition.

Why do you want to encrypt your boot partition?

TheStupid 09-01-2007 07:11 PM

because Windows keep admin password in the boot partition.

PGP would do it.

TheStupid 09-02-2007 11:56 PM

PGP is not free.

I've merged two similar threads.

Remove windows?

You could try compusec (http://www.ce-infosys.com/english/index.html). However, I have never used it myself (neither windows nor Linux) so I can't say much to it. It used to have the reputation of being pretty unreliable.

In Linux I'd really recommend to use dm_crypt for disk encryption.

Edit: Oh, in case you try compusec, please share your experience. I'd be interested to know :)

I'm also working on some options for the installation to either store the encryptions keys and related files on the cd, or upload/download from an ssh server.
