Windows: TrueCrypt

Lately, encryption has been on everyone’s mind. With the latest press about PGPDisk, people have been going nutty over disk encryption.

TrueCrypt
is a Windows XP/2000/2003 program that can create a virtual encrypted disk or a hard disk partition or device.
Main Features:

  • It can create a virtual encrypted disk within a file and mount it as a real disk.
  • It can encrypt an entire hard disk partition or a device, such as USB memory stick, floppy disk, etc.
  • Provides two levels of plausible deniability, in case an adversary forces you to reveal the password:
    1) Hidden volume (more information may be found here).
    2) No TrueCrypt volume can be identified (TrueCrypt volumes cannot be distinguished from random data).
  • Encryption algorithms: AES-256, Blowfish (448-bit key), CAST5, Serpent (256-bit key), Triple DES, and Twofish (256-bit key). Supports cascading (e.g., AES-Twofish-Serpent).
  • Based on Encryption for the Masses (E4M) 2.02a, which was conceived in 1997.
