Linux Unified Key Setup

Here are some notes that I took about setting up LUKS when studying for the RHCSA. I felt that this would be appropriate to post after the recent issues with TrueCrypt.

Disk Encryption

If I remember correctly, you can’t do whole disk encryption with LUKS after the fact. Meaning, you can use LUKS to do whole disk encryption after the operating system has been installed. You can, however, create a back up of a partition like /home, encrypt it, then restore /home to your newly encrypted partition. I’ll play around with this soon and get some solid details available for those of you looking for an TrueCrypt alternative for Linux. For now, I hope that this helps.
