Introduced XTS mode of operation, which is more secure than LRW mode. This release phased out support of 64-bit block ciphers, disallowing creation of new containers using the Blowfish, CAST-128, or Triple DES algorithms. In the Windows version, it introduced support for dynamic (sparse file) volumes.Īdded support for Windows Vista, support for file systems using sector sizes other than 512 bytes. Īdded various features to the Linux version, such as the ability to create volumes, change passwords and keyfiles, generate keyfiles, and backup/restore volume headers. LRW mode also neutralized an exploit that could (under certain circumstances) be used to compromise the plausible deniability of a TrueCrypt volume by allowing it to be distinguished from random data. Added the Serpent and Twofish algorithms, along with cascaded cipher support.Īdded portable 'Traveller mode', along with new volume mounting options such as being able to mount as 'read only'.Īdded support for Linux, x86-64, Big Endian machines, keyfiles, hot keys, ability to protect hidden volumes against corruption when their outer volumes are mounted, favorite volumes, the Whirlpool hash algorithm, and language packs.Īdded LRW mode, which is more secure than CBC mode for on-the-fly storage encryption. The official TrueCrypt domain moved back to again at the beginning of May 2005, and the SourceForge website redirects to there.Īdded hidden volume support for containers. Version released on, which became the official TrueCrypt domain. Added RIPEMD-160, size of a volume was no longer limited to 2048 GB, ability to create NTFS volumes. This release was made under original E4M license. New release due to licensing issues relating to the GNU General Public License.

Release made under the GNU General Public License, and signed as the TrueCrypt Foundation – previous versions were signed by TrueCrypt Team. Removed support for Windows 98 and ME because the author of the Windows 9x driver for E4M (the ScramDisk driver) gave no permission that would allow his code to be used in projects derived from E4M. Added plausible deniability for containers (although due to its simplistic nature, the practical value of the 'plausible deniability' offered in this version is debatable), and various bugfixes and improvements over E4M.

Featured support for Windows 98, ME, 2000, and XP. However, E4M was discontinued in 2000 as the author, Paul Le Roux, began working on commercial encryption software. TrueCrypt is based on Encryption for the Masses ( E4M), an open source on-the-fly encryption program first released in 1997.
