Next we'll relocate your home folder and then recreate it, but now empty (to serve only as a mountpoint for the encrypted volume). Log out and log back in as the new user or hit ctrl+alt+f1 to go straight to the commandline. Otherwise let's make a new user and allow it to sudo. If you already have another admin user you can log in to skip this step. Now we need to copy your existing home folder into the encrypted volume, but we can't do that while you're logged in. Tar -xzvf truecrypt-7.0a-linux-圆4.tar.gzįor some reason I had to make the file executable:įollow the simple installation procedure, then create your encrypted volume:
#UBUNTU TRUECRYPT ALTERNATIVE PASSWORD#
(Of course there's probably a way to pass the password not in plaintext that I didn't discover.) This process can be done using the console package, but requires saving the encryption password in plaintext nullifying any improvement in security. :evil:Ī little step-by-step tutorial for the process I used (Ubuntu 10.04 圆4):ĭownload the appropriate Standard Linux package for TrueCrypt from: The 'work' folder itself should be 99.99% secure provided you've used a long random password (and nobody captures you and tortures the password out of you). For that you would need whole drive encryption. It is not 100% secure though, as you're only encrypting that users files and settings, and not your logs or swap space. It's pretty easy to setup, and lets you run a mix of encrypted and non-encrypted users on the same machine.

Pressing Cancel on the password prompt will go on to the login screen, letting you use the other users without mounting the truecrypt image. Now when you boot the computer, just before the login screen you'll get a popup asking you for the password for workimage.tc (it also asks when switching users.or complain that it's already mounted if it is). # Stolen from the debian kdm setup, aren't I sneaky in my case I called the file workimage.tc and placed it in /home, but you can place it anywhere as long as the 'work' user owns it and can read and write to it.
#UBUNTU TRUECRYPT ALTERNATIVE HOW TO#
You'll find the instructions for how to on the web. create an encrypted file/disk image (not partition). deb package for it that's easy to install. create a new user (let's call him or her 'work') Quickly and not in too much detail you can do the following: If you have a user on your laptop, such as one you use for work related material, that you want to secure.but you don't want to encrypt the whole drive, this is for you. I'm running Ubuntu 8.10, but it might work fine with other versions too. There may be a limit to how many total protectors can be assigned to a partition, but I've never hit it.This was something handy I discovered yesterday that I thought I might share. You can always remove or add protectors after the disk is encrypted, so you can purge all recovery options if you really wanted to. Depends on your tastes, or if it's being deployed to end users who may need to receive a recovery password to a laptop on the road over the phone. Recovery Keys are significantly stronger. They are limited to 48 numeric characters, and thus the easiest to brute force. if you use a TPM chip to encrypt using Bit locker, and say the TPM chip is destroyed, it would in essence be impossible to ever recover the encrypted data?īitLocker cannot be enabled on a bootable device unless a recovery method is generated and saved to a USB device or Active Directory.įor my personal devices I always disable Recovery Passwords.

Dumb question, since I never had a TPM chip to just mess with.
