Sometimes in your Linux life, you want to carry your data on a disk, but well encrypted so no one else can steal and read it. This article describes how to format and encrypt a disk. It uses SUSE Linux 11.1 as example, but it should work same or similar with any distribution.
Encrypt it
- Start the disk partitioner
yast2 disk
- Select a partition you want to format or a disk where you want to add an encrypted partition
- Choose Format partition and "encrypt file system"
- If you get an information that you need to install "pam_mount", allow this
- choose "next"
- enter a password for your system => next => finish
Test it
# cryptsetup -v luksOpen /dev/sdd1 blah Enter LUKS passphrase: key slot 0 unlocked. Command successful.
# mount /dev/mapper/blah /mnt/test
