I'm looking for a recommendation on a method that favours simplicity and reliability (performance is not a major concern). If you distribution ships pam_mount then it and dm_crypt work well together to encrypt /home/$USER. I use it and it just works. If you have a machine used mainly by you, then you can use a real/LVM partition rather than a loopback filesystem as the dm_crypt storage. This takes out a lot of the configuration complexity. If you use LVM then you needn't fret about getting the partition size wrong (although growing the encrypted file system is more work than it should be). You should also use dm_crypt to encrypt the swap partition, or dd /dev/random into swap as part of your shutdown. Bloody annoyingly the Linux suspend-to-disk has no option to send the suspended memory through encryption before it stores it to disk. So you can't use suspend and stay safe if someone nicks your laptop. -- Glen Turner Tel: (08) 8303 3936 or +61 8 8303 3936 Australia's Academic Research Network www.aarnet.edu.au -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
RE: [SLUG] Simple and reliable home folder encryption for Ubuntu 6.10
Why not just encrypt the the documents you need Some products will even append the encrypted data to the end of an image file so that when you open the file it looks like a picture. and the only clue that there is anything more than meets the eye is that the image file is bigger than it actually needs to be I believe that is the encryption that I would prefer and If I could find a program to do this in Linux I would be very happy and dance around going Yay ! -Original Message- From: Ben [SMTP:[EMAIL PROTECTED] Sent: Tuesday, November 28, 2006 7:22 PM To: slug@slug.org.au Subject:[SLUG] Simple and reliable home folder encryption for Ubuntu 6.10 I need to encrypt the home folder on my laptop and desktop.

I've heard lots of good things about http://www.truecrypt.org/ - never used it myself though. It sounds like it's probably overkill for what you're looking for...
