Why does the world need another full disk encryption (FDE) for ubuntu howto? The cipher parameter specifies the cipher to use for encryption and can be either AES-XTS128-PLAIN64 or AES-XTS256-PLAIN64. Hayden (UK2 VPS) wrote: I'm assuming that it's based on the unattended server needing to reach the Mandos server to provide the encryption key in order to boot, so in theory if someone clones your disks or steals them to use elsewhere later that they'll be unable to contact the Mandos server and thus won't decrypt. For this, we need to add a network hook  by creating a file in /etc/mandos/network-hooks.d containing the necessary commands to bring the network up. While previously it could be setup manually, with their new installer rolled out over the past few months, there is support for setting up full-disk encryption using LUKS as part of the installation process. Box1 will be identified by MandosServer1 using an OpenPGP key; each client (in this case Box1 but I could have many) has one unique key. The script will prompt for password for the drives.

Oracle VM VirtualBox 5.0 allows for encrypted virtual disk images by leveraging AES algorithm in XTS mode (128-bit or 256-bit); since the DEK is stored as part of the virtual machine configuration file, encryption introduces a further security feature that will ask for a password while starting the virtual machine. The kernel to include the dm_crypt kernel module. I would strongly caution you against doing full disk encryption if you care about the data on this server at all (and if you don't, why encrypt it?).
