Install veracrypt linux5/15/2023 ![]() ![]() You can avoid this risk with full system encryption (e.g., as set up by the Linux installer on Ubuntu) because this also encrypts the swap partition. On Windows, VeraCrypt's capabilities go much further: In the hidden inner container on Windows you can install a second hidden operating system whose existence is not demonstrable ( Figure 8). The special bootloader used for this does not work with Linux, and a posting from the VeraCrypt forum suggests that this situation is not likely to change any time in the near future. įigure 8: On Windows, VeraCrypt supports encrypting a complete operating system in a hidden partition. The Linux version does not have such a function. Of course, the free operating systems offer many well-known solutions: cryptsetup, a tool that offers full system encryption and comes with many Linux installers, has been able to unlock VeraCrypt volumes since version 1.6.7 from spring 2015. However, both Ubuntu 15.10 and openSUSE 42.1 still use older versions only Arch Linux already uses the current Cryptsetup release. It relies on a shell script to unlock the root filesystem embedded in the initial ramdisk, which is a file archive the kernel mounts provisionally as root at bootup. This archive contains kernel modules for the filesystems and a shell. Scripts create the conditions for mounting the final root filesystem. To cooperate with VeraCrypt volumes, you need to extend the standard version of this script for users with shell skills, this is not too difficult. The initial ramdisks of other distributions work in a similar way to those for Arch, which is why the process can be transferred in principle to this script. Listing 1 shows a section of the /usr/lib/initcpio/encrypt shell script, which asks for the password that will unlock the root filesystem. Line 5 shows the call to dm-crypt via cryptsetup with the parameter -type luks, which is the most common encryption format for Linux partitions. In addition to the root partition, an encrypted system needs an unencrypted boot partition, for which you need to create another 100MB partition. ![]() You replace with the identifier for the matching device file and copy to it the contents of the /boot directory from the current system. On the mirrored system, first change the fifth line in /etc/default/grub to: GRUB_CMDLINE_LINUX="cryptdevice=/dev/sd:veracrypt1 vera=1" What now follows are some steps already familiar to Arch Linux users from the initial installation of their system. ![]() The cryptdevice keyword points to the partition encrypted with VeraCrypt. The colon is followed by the name of the mapper in /dev/mapper/ (e.g., veracrypt1 here), which VeraCrypt uses to access the currently mounted partition.Ĭopy the modified vencrypt script available online to the /usr/lib/initcpio/hooks/ directory. To be able to install in the initial ramdisk, you need to duplicate /usr/lib/initcpio/install/encrpyt as vencrypt. The HOOKS line responsible for this might then read as follows: HOOKS="base udev autodetect modconf block filesystems keyboard keymap vencrypt fsck" Now register the modified vencrypt script under /etc/nf optionally, replace the existing original Arch Linux encrpyt version. The order is important: vencrypt needs to follow filesystems and keyboard but must occur before fsck. The keymap lets you change the keyboard mapping if needed otherwise, leave any existing hooks in your system unchanged. Now it is time to use chroot (change root) to change to the new system. The arch-chroot script from the Arch Linux installation medium handles this task you can call it with. ![]()
