Well, you might be wondering, what the hell is Truecrypt? Well, Truecrypt is a program that allows you to encrypt loads of data, and it's super easy to do. So follow along. The methods of encryption include AES-256, Serpent, and Twofish(a combo of the AES and Serpent algorythyms). If you're wondering, Twofish is my personal favorite.
T r u e C r y p t Free open-source disk encryption software for Windows Vista/XP, Mac OS X, and Linux 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.
"Provides two levels of plausible deniability, in case an adversary forces you to reveal the password:
1) Hidden volume (steganography) and hidden operating system.
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. Further information regarding features of the software may be found in the documentation.
Well, either that or go here. Click on downloads and download your version, whether it be for Mac os x or Windows. I myself, would not reccomend you downloading the source code and changing it, as one little mistake will cause the whole file to go corrupt. But, Im not you, am I?
