No, dude, read the tutorial, it's actually pretty cool how it works.
Ah.. that is rather interesting.
QUOTE('TrueCrypt Hidden Volume') said:
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.
I'm not sure if that was mentioned last time I read up on TrueCrypt, or if I just skipped over it.
It was interesting to read about and mess around with, but served no practical use for me.
What I like more though is the Deniable Encryption:
http://en.wikipedia.org/wiki/Deniable_encryption#ScenarioQUOTE('Deniable Encryption')
Scenario
Deniable encryption allows the sender of an encrypted message to deny sending that message. This requires a trusted third party. A possible scenario works like this:
[*]Alice is the wife of Bob, who suspects his wife is engaged in adultery. She wants to communicate with her secret lover Carl. She creates two keys, one intended to be kept secret, the other intended to be sacrificed. She passes the secret key (or both) to Carl.[*]Alice constructs a harmless message M1 about some boring stuff for Carl (intended to be revealed to Bob in case of discovery) and a burning love letter M2 to Carl. She constructs a cipher-text C out of both messages M1, M2 and emails it to Carl.[*]Carl uses his key to decrypt M2 and possibly M1 (in order to know the fake message, too).[*]Bob finds out about the email to Carl, becomes suspicious and forces Alice to decrypt the message.[*]Alice uses the sacrificial key and reveals the message M1 about the boring stuff to Bob. Since Bob does not know the other key, he has to assume that there is no other message M2.
Another possible scenario involves Alice sending the same ciphertext to Bob and Carl, to whom she has sent different keys. Bob's key could decrypt the ciphertext to a claim that Carl has maligned Bob, and Carl's key could decrypt the ciphertext to a claim that Bob has maligned Carl. Under the assumption that neither Bob nor Carl can find out each other's keys, Alice's ruse would never be discovered unless Bob and Carl find out that they have different keys.
