TrueCrypt 7.0 description

TrueCrypt is an open source software, which will help you hide your private data. It encrypts your files and documents on-the-fly; it can “lock” a single folder or even the whole drive, and supports Triple DES, AES, Blowfish, Serpent and other encryption algorithms. TrueCrypt is extremely powerful, and very easy to use.

Main 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.
• Parallelization and pipelining allow data to be read and written as fast as if the drive was not encrypted.
• 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.

Free open-source disk encryption software for Windows 7/Vista/XP, Mac OS X, and Linux.
