As the title says.

Is it possible to use full disk encryption on an Ubuntu 14 droplet?

My understanding is that it's not possible to use full encryption after installation. While it is possible to encrypt user folders and other selected areas.

I'm referring to the option of full encryption that is asked during installation of Ubuntu.

Not currently. While you could set up encryption on your /home directory it is not possible to enable full disk encryption on Ubuntu 14.04 droplets.

Ubuntu 15.04 droplets have user-managed kernels (meaning that it boots directly to the kernel within your filesystem) While it would not be officially supported it may be possible since you would be able to resize/create partitions but to the best of my knowledge this has not been attempted by any users.

    This is the only reference I can find to this. Do you have anywhere I can read more about these?

  • Many previous releases were set up to boot from a kernel image which was specified in the control panel. With recent updates to our systems user-managed kernels are now supported and will be as we release new and updated images.

    User-managed kernels simply means that the bootloader and kernel image inside your filesystem is used when booting your droplet, just as would happen with physical hardware. This is currently supported on Ubuntu 15.04 and FreeBSD droplets.
