[Cialug] Encrypting filesystems - WAS: OT: Macbook for sale

[Nathan C. Smith]

TrueCrypt is available for all 3 platforms, but I think the whole-disk system drive encryption only works on Windows.  It is so easy to use even a Windows user could do it.

I've never used the encrypting filesystems on Linux.  Are they easy to configure?  Is anyone on the list using one?  Can you boot from an encrypted filesystem?

For the truly paranoid you are supposed to use TrueCrypt, or something like it, and double-encrypt your hard drive.  An outside layer that is the one you reveal at gunpoint, - has a working OS and some legitimate looking files,  and the inside-super-secret layer that nobody knows about except you.

Too bad this is only supported (by TrueCrypt) under Windows and not Linux or MacOS.  What software alternatives are available for those platforms?

Well, if I had such sensitive and critical data that I needed to hide my operating system then it would probably be worthwhile tradeoff.

Considering that truecrypt works on Linux and Mac OS and that Linux has a lot of encryption options available to it, and the filesystem is opensource as well as the bootloader and the rest of the OS, I'm surprised that it isn't a supported operating system for this.

Maybe it changes too fast.
