TrueCrypt timestamps

In Security Now! Listener Feedback #36, Steve and Leo addressed a question about the timestamp of TrueCrypt containers not changing when the contents of the container change (transcript). This is part of TrueCrypt's plausible deniability.

There is a simple way to turn this off inside TrueCrypt. In version 5, click Settings, then Preferences. On the Security tab, there's a checkbox for "Preserve modification time of file containers". When unchecked, this will update the timestamp of the TrueCrypt container whenever its contents change.

In the Linux command-line version of TrueCrypt 4, you could use "--update-time" to do the same thing. This functionality has been removed in version 5, so I'm using the GUI version of 5 in Ubuntu Linux.

From the truecrypt 6.1a source code (Main/CommandLineInterrface.cpp line 309), you can see that this option is now available as


This turns off timestamp preservation, which is on by default.

@ vitorlazo:

It is working with Linux too.

1) Settings > Preferences > Register Security > disable "Preserve modification time of file containers" >
2) Register "System Integration" > enable "Do not use kernal cryptographic services"

After that the timestamp of the container changes whenever a file within the container is changed.

Another option on Linux with the command line is to simply "touch" the volume before you mount it. The "touch" command will change the modified time to now.

The difference between burritos, chimichangas, and enchiladas

I love Mexican food, but I'm embarrassed to admit that I always get confused between burritos, wet burritos, chimichangas, and enchiladas. Here are the descriptions, with the differences in bold and pictures following each description.

A flour tortilla wrapped around a filling (meat, beans, vegetables, etc)

wet burrito
A burrito that's covered in red chili sauce and cheese. Because of the sauce covering, it looks like an enchilada, but it's made with a flour tortilla, whereas the enchilada is made with a corn tortilla.

A burrito that's deep-fried. Sometimes covered with cheese or another topping.

Considering retiring this blog

I'm seriously considering retiring this blog. When I started it in 2008, it was a place for me to share thoughts and links on a variety of topics. For at least the last year, however, it's just been a place where I re-post book reviews from Goodreads.

You can see all my book reviews on my Goodreads profile, and subscribe to my Goodreads RSS feed to be notified of new reviews. I also intend to keep blogging about WordPress, web design, and web-related topics on my OptimWise blog, which also has an RSS feed.

Would you miss this blog if I discontinued it? Please leave a comment.
