LUKS and Nuke key installtion on Ubuntu?
When you install Ubuntu there's an option to encrypt the installation. I didn't select that, can I still encrypt Ubuntu? I do not want to encrypt my home folder I would like to encrypt Ubuntu as if I did select that option on the setup process. Also I recently saw that Offensive Security added the NUKE key feature to Kali's encrypted partitioning and LVM option. Can I install that on Ubuntu as well?

This question came from our site for information security professionals.
The encryption Ubuntu offers on install is based on ecryptfs. That is file encryption and only encrypts the home folder. If you want a full block device encryption and a bootable Ubuntu you need to do it yourself manually. Search forluks(the encryption) &lvm(you need logical volumes because booting should be possible) & Ubuntu installation.

Yes, you can add the NUKE feature to Ubuntu crypsetup!
You need der sourcecode from crypsetup, the patch for cryptsetup-1.6.6...
Then you can compile new libcryptsetup and cryptsetup with nuke feature.
This patch is for 1.6.6-5 (Ubuntu 16.04), for other version you neeed other patch, please visit the link!
get the patch (take a look http://deriv.debian.net/patches/c/cryptsetup/)
sudo apt-get update
sudo apt-get install libgcrypt11-dev libdevmapper-dev libpopt-dev uuid-dev libtool automake autopoint debhelper xsltproc docbook-xsl dpkg-dev
sudo apt-get source cryptsetup
wget http://deriv.debian.net/patches/c/cryptsetup/Debian_cryptsetup_2:1.6.6-5_Kali_cryptsetup_2:1.6.6-5kali1.debian.patch
extract source code from cryptsetup
cd cryptsetup-1.6.6
now its time to patch
patch -p1 < ../cryptsetup-nuke-keys/cryptsetup.patch
please corret the path, in my folder i have modified...
after patching, create DEB files for ubuntu
dpkg-buildpackage -b -uc
now its time to install
sudo dpkg -i ../libcryptsetup*.deb
sudo dpkg -i ../cryptsetup*.deb
edit:
I have made a simple shell script to patch and compile cryptsetup for Ubuntu 16.04.
Please be careful!
run it with sudo!
#!/bin/sh
apt-get update
apt-get install libgcrypt11-dev libdevmapper-dev libpopt-dev uuid-dev libtool automake autopoint debhelper xsltproc docbook-xsl dpkg-dev
apt-get source cryptsetup
wget http://deriv.debian.net/patches/c/cryptsetup/Debian_cryptsetup_2:1.6.6-5_Kali_cryptsetup_2:1.6.6-5kali1.debian.patch
cd cryptsetup-1.6.6
patch -p1 < ../Debian_cryptsetup_2:1.6.6-5_Kali_cryptsetup_2:1.6.6-5kali1.debian.patch
dpkg-buildpackage -b -uc
After that, you can install with
sudo dpkg -i ../libcryptsetup*.deb
sudo dpkg -i ../cryptsetup*.deb
check with
cryptsetup --help | grep luksAddNuke
should look like
luksAddNuke - add NUKE to LUKS device
Now you can add nuke keys with
sudo cryptsetup luksAddNuke /dev/sda5
With a standard Ubuntu installation it is normal sda5 !
Now make a backup of the header!
sudo cryptsetup luksHeaderBackup /dev/sda5 --header-backup-file luks-backup
copy the file luks-backup on save location, if you wipe the header with nuke password, you can recover the header with linux live system!
make sure, that ubuntu update dont install the "normal" cryptsetup
sudo apt-mark hold cryptsetup-bin libcryptsetup4
check upgrade
sudo apt-get upgrade
looks like this
Die folgenden Pakete sind zurückgehalten worden:
cryptsetup-bin libcryptsetup4 linux-generic linux-headers-generic linux-image-generic ubuntu-core-launcher
If i have some time, i would create ppa.

The encryption Ubuntu offers on install is based on ecryptfs. That is file encryption and only encrypts the home folder. If you want a full block device encryption and a bootable Ubuntu you need to do it yourself manually. Search for
luks(the encryption) &lvm(you need logical volumes because booting should be possible) & Ubuntu installation.– therealmarv
