I have been using the open source encryption software TrueCrypt for a long time to keep my data secure on connected hard drives. The program has evolved over the years, and can now create encrypted file containers, encrypt full partitions and even the whole computer system.

TrueCrypt is that solid that its developers need to update it only once or twice a year. The last update dates back to September 2011 where support for Mac OS X 10.7 Lion was added to the application, and the update before that was almost a year before that.

Yesterday the first 2012 update was released. The change log over at the TrueCrypt website lists minor improvements and bug fixes as the only changes in TrueCrypt 7.1a. It does not go into further detail, other than stating that these have been applied to all supported operating systems.

TrueCrypt users can download the latest version of the application from the official project website. You need to close all TrueCrypt instances running on the system before the update can be installed.

Should you install the update if you are running a version of TrueCrypt that is not causing problems or issues on your system? I'd say you may still want to update to TrueCrypt 7.1a, considering that the update may have resolved rare bugs that you might experience in the future if you do not apply the update.

If you are a new TrueCrypt user you may be interested in our collection of TrueCrypt tutorials that we have published over the years. Here is a short selection of guides to get you started:

    Yesterday 13-Sep-2012, discovered that the issue that I had, with internet connectivity, had nothing to do with TrueCrypt 7.1a. But rather it was a Windows 7 issue. The very next update, where I had to reboot (windows patches) also lost internet connectivity. So TrueCrypt 7.1a was blameless. I have since reinstalled and have had no issues. The reboot issue, after installation, was a “quirk” of MS Windows 7. As odd as it sounds, Windows 7 internet connectivity was stalled, for some reason, after the reboot. It was easily cleared by simply opening the Control Panel resident Network and Sharing Center. Didn’t even need click on any button. The window opened, and internet connectivity was restored. Very odd indeed, as even another reboot did not clear it, without doing this.

      Sounds like one of those issues that are really hard to diagnose.

    Today 1-Sep-2012, had a little issue with the upgrade to TrueCrypt 7.1a.
    My System has Windows 7 Ultimate.
    Had TrueCrypt 7.1 installed, been using successfully, for 8 months.

    So after installing the upgrade 7.1a, the system needed to reboot.
    Did so.
    After the reboot I lost all internet connectivity.
    Couldn’t even ping my wireless Router. Confirmed that I was directly connected, i.e., unplugging the ethernet jack, lights stopped flashing, plugging it in again, flashes again.
    Confirmed all connections still functioning.
    Rolled back via System Restore, and once again had internet connectivity.
    I like TrueCrypt, would like to upgrade, but am now wary.

    Hi Martin,

    i have a container made from old truecrypt 7.0, do i need to create a new container when i update truecrypt? or i can re-use the old container?

      The container can be mounted in the new version as well.

    Thanks for the articles Martin. I’ve started using TrueCrypt after learning about the hidden encrypted volume function here. It’s the easiest thing to use.

    I’ve recommended to the U.S. DoD to include TrueCrypt in their LPS distribution for use in compromised locations.
