Short version of the question below.
Please help me understand the encryption features in Ubuntu 12.10. Installing Ubuntu, I opted both for the full disk encryption option as well as for the "encrypt home folder" option. It is my understanding that the encrypted partitions are mounted and deciphered when I turn my computer on.
I now like to know under what circumstances what partitions are dismounted and encrypted again. Obviously, all of them are dismounted when I turn my computer off. And obviously, not all of them are dismounted when I go into suspend or lock. But what about the home folder? Is it dismounted when my computer suspends or is locked? In other words: How secure is my data when I just go into suspend or lock my computer?
- Is the encrypted home folder dismounted when the computer is locked or goes into suspend?
- How secure is my data when my computer is locked but not shut down?
EDIT: Confused hibernate and suspend.
