TrueCrypt 6.2a

TrueCrypt 6.2a is a powerful software system for establishing and maintaining an on-the-fly-encrypted volume (data storage device). On-the-fly encryption means that data is automatically encrypted or decrypted right before it is loaded or saved, without any user intervention. No data stored on an encrypted volume can be read (decrypted) without using the correct password/keyfile(s) or correct encryption keys. Entire file system is encrypted (e.g., file names, folder names, contents of every file, free space, meta data, etc).

Major Features:

1. Creates a virtual encrypted disk within a file and mounts it as a real disk.
2. Encrypts an entire partition or storage device such as USB flash drive or hard drive.
3. Encrypts a partition or drive where Windows is installed (pre-boot authentication).
4. Encryption is automatic, real-time (on-the-fly) and transparent.
5. Parallelization and pipelining allow data to be read and written as fast as if the drive was not encrypted.
6. Provides plausible deniability, in case an adversary forces you to reveal the password:
7. Hidden volume (steganography) and hidden operating system.
8. Encryption algorithms: AES-256, Serpent, and Twofish. Mode of operation: XTS.
9. Further information regarding features of the software may be found in the documentation.

Enhancements:

• 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)
