Download TrueCrypt 4.0

TrueCrypt is an encryption program that can encrypt physical (a hard disk or a partition) and virtual volumes (a file that is accessed as a partition). A number of different methods can be used for encryption, such as AES (256-bit), Blowfish (448-bit), CAST5 (128-bit), Serpent (256-bit), Triple DES and Twofish (256-bit) . They can also be used sequentially so that a file is first encrypted with AES and then with Serpent.

TrueCrypt’s developers have released version 4.0, which has been ported to the Linux platform, allowing TrueCrypt volumes to be used on both Linux and Windows. The complete list with changes is unfortunately too long to list here and the included announcement looks like this:

We are pleased to announce that TrueCrypt 4.0 has been released. Among the new features is the ability to mount TrueCrypt volumes on Linux (TrueCrypt has been ported to Linux), ability to write to outer volume without risking that a hidden volume within it will get damaged, support for x86-64 (64-bit) and big-endian hardware platforms, support for Windows XP x64 Edition (64-bit) and Windows Server 2003 x64, full support for keyfiles, language packs, network drives, auto-dismount, hot keys, and many more. In addition to new functionalities, many optimizations have been made and several bugs have been fixed.
