In the case of you needing to prove the hidden volume does not exist, some people create a small hidden volume and leave it empty. require totally different strategies on your part. You need to make some assumptions about the methods your adversary is willing and/or able to employ to get your data.ĭealing with mafia, corrupt officials, prying roommates, etc. Next you need to evaluate the type of threat you are protecting agents. If you understand the details of volume headers and how they are embedded in the inner and outer volumes you will be able to answer your own questions about hidden volumes and other encryption issues.Įven when you understand the fundamentals you are still not done. In the case of Truecrypt, you must STUDY (not read) the manual. You will never achieve the level of understanding you need by asking questions on a forum. The only way you can have confidence in it is to really understand the details of how a hidden volume works with the encryption. Plausible deniability is a tricky subject for sure. A much better defence would be an attempt at wiping it (or just the header) before they can force you to open it. It's not a huge whole but none-the-less don't rely on it against a sophisticated attacker. You could of course have an excuse prepared for it. Now when forced to reveal the volume ideally you would NOT check that box and hence it would show as 6GB (the files size) in the event the attacker writes a file to test the actual size is true they overwrite the hidden volume destroying your data.Ī well versed attacker would also force you to check that box and (somewhat) ruin the plausible deniability. This mode is only supposed to be used when place files on the outer volume for plausible deniability. (I.E 6 GB volume 3 GB outer and 3GB hidden you would see the out volume as 3GB only) This would be suspicious as the entire drive/file shows 6GB. If you check the box that says "protect hidden volume from being overwritten" then when the outer volume is mounted it will only show up as the size of the out volume.
