True Crypt

Protect your sensitive data with this free open-source disk encryption software. Creates a virtual encrypted disk within a file and mount it as a real disk. Encrypt an entire hard disk partition or a device, such as USB flash drive. Automatically and transparently encrypt in real time.

The ultimate freeware encryption program, TrueCrypt is loaded with powerful features that those concerned with protecting their data from thievery should want--and have.

TrueCrypt provides two levels of plausible deniability, in case an adversary forces you to reveal the password: a hidden volume (steganography- more information may be found here); no TrueCrypt volume can be identified (volumes cannot be distinguished from random data). TrueCrypt uses encryption algorithms AES-256, Blowfish (448-bit key), CAST5, Serpent, Triple DES, and Twofish. It is based on Encryption for the Masses (E4M) 2.02a, conceived in 1997.
Version 6.2 includes the I/O pipeline now uses read-ahead buffering, which improves read performance especially on solid-state drives, typically by 30-50%.


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.
