To whom it may concern, I will be implementing the use of dmcrypt-LUKS on a project I am work on, but I need explicit verbage of some features that I cannot find answers to. 1.
When LUKS is applied to a partition of a drive, is decrypted data only stored in memory and never written back to the drive (unencrypted). 2.
Is there any caching of decrypted data; If accessed again, is it read from memory or decrypted again? 3.
What are the implications of a system that is shut down (powerloss, critical failure, etc.) without the command “lucksClose” issued to an encrypted device? Respectfully, Edwin Ruiz Systems Administrator, VCS21 Critical Networks
