LUKS

 

Recently during an engagement, I encountered Linux Unified Key Setup (LUKS), a partition encryption method used in various versions of Linux. Some companies require PGP full disk encryption for their Windows workstations and LUKS is the Linux alternative to maintaining the company encryption policies for those that allow Linux workstations.


This Blog is not to tell you how LUKS works but to explain the way to deal with it should you come across it du...
