Linux Full Disk Encryption (LFDE) is a tool designed to provide Linux with a means to do true full disk encryption (FDE).
What do we mean by "true" full disk encryption? It means exactly what we say. The LFDE tool configures your entire Linux hard disk to be encrypted. Our approach is different to the default encryption built into distributions such as Ubuntu and Fedora because we don't leave the /boot partition unencrypted on the hard disk. We move it to a bootable USB key along with a far more secure key to unlock the hard disk.
