TrueCrypt is a software system for establishing and maintaining an on-the-fly-encrypted volume (data storage device). On-the-fly encryption means that data are automatically encrypted or decrypted right before they are loaded or saved, without any user intervention. No data stored on an encrypted volume can be read (decrypted) without using the correct password/keyfile(s) or correct encryption keys. Entire file system is encrypted (e.g.., file names, folder names, contents of every file, free space, meta data, etc).

Files can be copied to and from a mounted TrueCrypt volume just like they are copied to/from any normal disk (for example, by simple drag-and-drop operations). Files are automatically being decrypted on-the-fly (in memory/RAM) while they are being read or copied from an encrypted TrueCrypt volume. Similarly, files that are being written or copied to the TrueCrypt volume are automatically being encrypted on-the-fly (right before they are written to the disk) in RAM. Note that this does not mean that the whole file that is to be encrypted/decrypted must be stored in RAM before it can be encrypted/decrypted. There are no extra memory (RAM) requirements for TrueCrypt.

Preparing your System

sudo aptitude install sun-java6-jre python-pexpect build-essential

Now you need to download the truecrypt .deb package from here for your ubuntu version.

Now you should be having truecrypt-4.3a-ubuntu-7.10-x86.tar.gz file extract this using the following command

sudo tar xzvf truecrypt-4.3a-ubuntu-7.10-x86.tar.gz

Now you have truecrypt-4.3a folder

Go into the folder and install .deb package

sudo dpkg -i truecrypt_4.3a-0_i386.deb

Now you should be able to see the following error

Selecting previously deselected package truecrypt.
(Reading database ... 133570 files and directories currently installed.)
Unpacking truecrypt (from truecrypt_4.3a-0_i386.deb) ...
dpkg: dependency problems prevent configuration of truecrypt:
truecrypt depends on dmsetup; however:
Package dmsetup is not installed.
dpkg: error processing truecrypt (--install):
dependency problems -- leaving unconfigured
Errors were encountered while processing:

To fix the above error run the following command

sudo apt-get -f install

This will complete the TrueCrypt installation.

tcgui -- TrueCrypt GUI

These functions are integrated already:

Mount/Unmount TrueCrypt volumes
Create volumes easily with the wizard
Change volume password easily
Backup / Restore volume headers
Manage your favourites
Mount several volumes with one click

The tcgui looks similar to the windows GUI for truecrypt

You need to download tcgui from here

now you have tcgui.0.4.tar.gz file extract using the following command

sudo tar xzvf tcgui.0.4.tar.gz

Now you have tcgui-0.4 go in to this folder run the following command

cd tcgui-0.4

sudo bash $USER

Note:- simply copy & paste the above command

Using tcgui

If you want to open goto Applications--->Accessories--->TrueCrypt GUI

Click on "Yes" if you agree with the warranty agreement.

Once it opens you should be able to see similar to the following screen

Uninstall tcgui

If you want to Uninstall the TrueCrypt GUI open a terminal and enter the following command

sudo bash /usr/share/tcgui/

Note: The group "truecrypt" will not be deleted and the changes in the sudo configuration will not be restored.

    If you download and install TC 5.1a for Linux, you get a GUI built in, no extra packages. It looks and acts just like I remember from the Windows client.

  2. jj says:

    I do not believe you need to add the GUI in that Truecrypt 5.1a (Feb 08) includes it.

  3. ændrük says:

    How does this compare with using something like EncFS+gui?

  4. apeekaboo says:

    Truecrypt 5.1a works almost as good as the Windows-version of it. I’m only missing the ability to create hidden containers within a truecrypt container in Linux. You can however create the hidden container in Windows and then use it in Linux, no problem.

  5. Andrew says:

    I’m trying to figure out why all the guides on this site use Ubuntu 7.10…

  6. ok says:

    this is not working.

  7. hiero2 says:

    As of May 26, 2010, this how-to is outdated. Truecrypt no longer offers a .deb download. Their installation tar simply extracts binary and assorted files to /usr/share directories. Can be made functional by messing about as superuser.
