Keep Confidential Files – Confidential…

We all have some of other type of information on our PC’s that we would rather keep private.   It might be those electronic payslips that you saving. It may be those excel spreadsheets with your budget information. It may even be those *cough* *cough* pictures.  Long story short we all have information that we would rather keep private.

About 4 years ago I was introduced to a program called TrueCrypt by  a staff member in our Forensics department.  He said by using TrueCrypt he was able to keep all his information secure from prying eyes, and it also made backing up an easy exercise.

I did a Google search and found the website – http://www.truecrypt.org.  To quote the website, TrueCrypt’s features are:

– Free open-source disk encryption software for Windows 7/Vista/XP, Mac OS X, and Linux

– Creates a virtual encrypted disk within a file and mounts it as a real disk.

– Encrypts an entire partition or storage device such as USB flash drive or hard drive.

– Encrypts a partition or drive where Windows is installed (pre-boot authentication).

– Encryption is automatic, real-time (on-the-fly) and transparent.

– Parallelization and pipelining allow data to be read and written as fast as if the drive was not encrypted.

– Encryption can be hardware-accelerated on modern processors.

– Provides plausible deniability, in case an adversary forces you to reveal the password:

– Hidden volume (steganography) and hidden operating system.

The quick and easy explanation on how it works is that you create a file on your hard drive, using TrueCrypt, that you can mount then as a drive letter on your PC.  This drive acts like any other drive, but it is encrypted and once you reboot or dismount the drive, unless someone knows what the filename is and what the password is then your data is secure.   As this is one file you need only copy one file to another location to make a backup all your secure data.

The interface, by being plain, makes it a breeze to use the app:

Here are the options for creating the encrypted file.  You can call the file ANYTHING. Hide it by calling it pagefile.sys in a folder (not the root) if you like. Call it file without an extension. You have options to encrypt a whole drive also if you like.

Here are your different encryption options for the volume:

Have a look at the website and download it.  You will be surprised just to find how easy it is to secure your files.
