When you are working for instance, on a project that should be hidden from other eyes, it is a good idea to secure it. All that can be done by TrueCrypt.

TrueCrypt – is an encrypting software that provides you with all functions that are needed to secure your secret information. There are several main features, that are pretty useful:

  • Creating a virtual disc (a file that is your disc; where you can put other files.)
  • Encrypting entire partition, storage device such as USB, or hard drive.
  • Encrypting a partition that contains Windows. (pre-boot)
  • Creating a hidden volume.

(there are more features as well!)

After some few experiments, I would say that the best way to secure your files is by “Creating a virtual disc“. However, it depends on the purpose as well. If your entire computer is to be protected, it is better to “Encrypt the Windows partition” and all other internal discs on the computer. By doing this kind of encryption, you will be prompted to enter a secret password each time the Windows boots. The good thing is, if you get your computer stolen, the information will remain inaccessible for all except you. Correctly speaking, it will remain accessible for anyone with the password. If you suddenly forget the main password, you can say “bye” to the information of yours.

By creating a virtual drive, your information (folder system with all files) will remain safe in one big file (the size is assigned when creating it). When you will encrypt your entire drive (Windows partition) it is good to take a backup of all your information, because it might be something that causes data lose (eventually a bug).

There are also an opportunity to hide a volume. It is also a good advanced feature that is build into TrueCrypt.”The principle is that a TrueCrypt volume is created within another TrueCrypt volume (within the free space on the volume). Even when the outer volume is mounted, it should be impossible to prove whether there is a hidden volume within it or not*, because free space on any TrueCrypt volume is always filled with random data when the volume is created** and no part of the (dismounted) hidden volume can be distinguished from random data. Note that TrueCrypt does not modify the file system (information about free space, etc.) within the outer volume in any way.“, (read more).
