This article has been updated for Fedora 8.
This tutorial explains how to encrypt a partition on a hard drive, specifically the fourth partition on a hard drive that will contain the home directory. Keep in mind that the root directory, the tmp directory (if it is not on the same partiton as the root directory), and the swap partition would also have to be encrypted to ensure data privacy.
- Initialize LUKS on the new partition for /home (sda4) with: cryptsetup --key-size 256 --verbose --verify-passphrase --cipher aes-cbc-essiv:sha256 luksFormat /dev/sda4
- Start up the encrypted file-system with: cryptsetup luksOpen /dev/sda4 home
- Format with: mke2fs -j /dev/mapper/home
- Add a line to /etc/crypttab. For example: home /dev/sda4 none luks
- Add a line for /home to /etc/fstab. For example: /dev/mapper/home /home ext3 defaults 1 2
- Mount up the encrypted /home and copy data to it.
