I probably should have said on-the-fly encryption because that’s what TrueCrypt does.  TrueCrypt gives a free way to encrypt a file, a bunch of files, or your entire OS installation.

The following operating systems are supported:

  • Windows Vista
  • Windows Vista x64 (64-bit) Edition
  • Windows XP
  • Windows XP x64 (64-bit) Edition
  • Windows Server 2008
  • Windows Server 2008 x64 (64-bit)
  • Windows Server 2003
  • Windows Server 2003 x64 (64-bit)

TrueCrypt supports the following encryption algorithms:

Algorithm Designer(s) Key Size
(Bits)
Block Size (Bits) Mode of Operation
AES J. Daemen, V. Rijmen 256 128 XTS
Serpent R. Anderson, E. Biham, L. Knudsen 256 128 XTS
Twofish B. Schneier, J. Kelsey, D. Whiting,
D. Wagner, C. Hall, N. Ferguson
256 128 XTS
AES-Twofish 256; 256 128 XTS
AES-Twofish-Serpent 256; 256; 256 128 XTS
Serpent-AES 256; 256 128 XTS
Serpent-Twofish-AES 256; 256; 256 128 XTS
Twofish-Serpent 256; 256 128 XTS

The following hash algorithms are supported:

TrueCrypt allows you to specify a file as the encrypted disk.  This is sort of like a virtual disk.  You can also encrypt an external drive, like a USB drive or external drive.  Or, you can encrypt the entire OS.  In this method, you will be asked for a passphrase before you can even enter the OS.
