TrueCrypt can create a virtual encrypted disk within a file and mount it as a real disk, or an entire hard disk partition or a device, such as USB memory stick, floppy disk, etc. This software provides two levels of security: a hidden volume (more information may be found here), and a volume cannot be identified (no part of the volume can be distinguished from random data). It utilizes the following encryption algorithms: AES (256-bit key), Blowfish (448-bit key), CAST5 (128-bit key), Serpent (256-bit key), Triple DES, and Twofish (256-bit key), and also supports cascading (e.g., AES-Serpent-Twofish). It is based on Encryption for the Masses (E4M) 2.02a, conceived in 1997. Features: - 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.
- Provides plausible deniability, in case an adversary forces you to reveal the password: Hidden volume (steganography) and hidden operating system.
- Encryption algorithms: AES-256, Serpent, and Twofish. Mode of operation: XTS.
What's New in version 6.2a: - Improved file container creation speed on systems having issues with write block sizes greater than 64 KB. (Windows)
- The 'Device not ready' error will no longer occur when the process of decryption of a system partition/drive is finished. (Windows)
- Other minor improvements and bug fixes. (Windows, Mac OS X, and Linux)
