TrueCrypt. A free Open Source encryption program which can render your disk, folders or files completely un-readable in a split of a second. Or sooner. Not only that, but the software can make whole chunks of your hard drive disappear in a mist of ‘where did it go?’ magic. Perfect for hiding all those Barry Manilow tracks you’re so anxious about. Available for Windows, Mac and Linux.
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. # 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: XTS.
