Directory encryption (By using Truecrypt)
The last recipe of
this chapter will be about information privacy. We will use TrueCrypt to hide
important and secret digital information from public eyes with encryption keys.
How to do it...
Let's perform the following steps:
1. 1. Install TrueCrypt by clicking on the Applications menu and navigating to
BackTrack | Forensics | Digital Anti Forensics
| install truecrypt. Click on Install TrueCrypt and follow the
onscreen directions:
1. 2. Launch TrueCrypt from Applications | BackTrack | Forensics | Digital Anti Forensics
| truecrypt to find a window
similar to the following screenshot:
3. Click on Create Volume to start TrueCrypt Volume
Creation Wizard.
4. Leave the default
option and click on Next.
5. Select Standard TrueCrypt
volume and click on Next.
6. Click on the Select File… button and specify a
name and location for the new TrueCrypt volume. Click on Save when done:
7. Click on the Next button and select the
encryption and hash algorithm we want to use.
8. In the next screen,
we'll specify the amount of space we want for the container.
9. Now, we need to
type the password for our volume. Once done, click on Next.
10. Choose the
filesystem type.
11. Select the
cross-platform support depending on your needs.
12. At the next
screen, the wizard asks us to move around the mouse within the window to
increase the cryptographic strength of the encryption keys. When done, click on
the Format button.
13. The formatting
will start and ends with the creation of the TrueCrypt volume. Click on OK and Exit.
14. We're now back to
the TrueCrypt window.
15. To decrypt our volume, pick a slot from
the list, click on Select File…, and open our created volume.
16. Click on Mount and type your
password. Click on OK when done:
17. We can now access the volume by
double-clicking on the slot or through the mount directory. Save files in it
and when finished, simply click on Dismount All.
