The principle is that a TrueCrypt volume is created within another TrueCrypt volume (within the free space on the volume). Even when the outer volume is mounted, it is impossible to prove whether there is a hidden volume within it or not, because free space on any TrueCrypt volume is always filled with random data when the volume is created* and no part of the (dismounted) hidden volume can be distinguished from random data. Note that TrueCrypt does not modify the file system (information about free space, etc.) within the outer volume in any way.
The password for the hidden volume must be different from the password for the outer volume. To the outer volume, (before creating the hidden volume within it) you should copy some sensitive-looking files that you actually do NOT want to hide...
Szóval akár el is árulhatod a jelszót (mert van egy másik, beljebb lévő szint xD).
A titkosításnak igenis van létjogosultsága mindenhol. És egy második személy nélkül szinte lehetetlen kifogni rajta..
