TrueCrypt - Open Source Volume Encryptor


http://www.truecrypt.org/

Free open-source disk encryption software for Windows Vista/XP/2000 and Linux

Main Features:

  • Creates a virtual encrypted disk within a file and mounts it as a real disk.
  • Encrypts an entire hard disk partition or a storage device such as USB flash drive.
  • Encryption is automatic, real-time (on-the-fly) and transparent.
  • Provides two levels of plausible deniability, in case an adversary forces you to reveal the password:
  • 1) Hidden volume (steganography – more information may be found here).
  • 2) No TrueCrypt volume can be identified (volumes cannot be distinguished from random data).
  • Encryption algorithms: AES-256, Serpent, and Twofish. Mode of operation: LRW.

    WHAT IS HIDDEN VOLUME ?
    Hidden volume has two layer
    Outer layer and inner layer

    When you create a hidden volume,
    you will prompt to set password for outer layer
    which allow to be revealed.

    While inner layer is actually the most 'private' data

    It may happen that you are forced by somebody to reveal the password
    to an encrypted volume.
    In this case, you may just reveal outer layer password.

Mount Method. You can set as read only and protect your hidden volume option.



Success Mounted. and you will get an extra drive z: with your data inside.
Right click and open it. You may want to store your 'private' data inside :)
