TrueCrypt

This is a block encryption technique, but which double encrypts the blocks
so it can not even be reconised by a third party as an encrypted partition.
(I think).

It was originally written for Windows 2000/XP/2003, but is available under
linux in source code.

Current version (4.1) Can not however create TrueCrypt partitions on linux,
as this was written with windows GUI, a port is in progress. Solutions inlude
using a dual boot or vmware to create the partition under windows.

Linux Documentation is also scarce.

Also efforts are to intergerate this with LUKS cryptsetup, dm-crypt methods.

Status:  Keep a watch on it.
