View Full Version : [ubuntu] Whole disk encryption Questions

February 2nd, 2009, 07:43 PM
I have a number of questions regarding disk encryption. What I need to set up is an encrypted dual-boot environment, preferably with PGP WDE/Windows XP (because this is the supported standard here where i work) and whatever Linux will use. I have one hard drive with which to do this, a 500 GB drive. ( Which is a limitation of the laptop. )

I'm considering options such as TrueCrypt, LUKS, and loop-AES. I'm not sure how I would do full disk encryption (root, swap, etc) with TrueCrypt. LUKS looks like it is supported, even by GUI with Intrepid, however, I found a reference not to use it here: http://ubuntuforums.org/archive/index.php/t-401222.html, which says:


It's recommended NOT to use cryptoloop, LUKS, dm-crypt in kernels prior to 2.6.10, bestcrypt, truecrypt versions prior to 4.1, or loop-AES in single-key mode.

The recommended full disk encryption solution is loop-AES (http://loop-aes.sourceforge.net/) in multi-key mode with encrypted swap! This achieves maximum available security for your data. Available ciphers are AES, Blowfish, Serpent, and Twofish.


Implied in the description of what I need to have working is that Windows / PGP WDE would need to be set up first, consuming one primary partition on the drive. This may warrant consideration, it may not, if LUKS is now a more viable alternative and/or the process can work with extended partitions... I'm not sure how to even set up a dual boot with PGP WDE/Windows...
