Sometimes at office or even at home i don't want certain part of my hard drive not accessible by anyone. Well you can hide your folders but is it giving you the optimal protection, i don't think so. TrueCrypt is a open source software comes with a highly secured protection systems. The algorithms are so difficult to break that it might take a few billion years to break the password. TrueCrypt can be used on windows xp/vista or linux platforms. Actually what it do is to create a physical file on a hard disk and encrypt it with very strong protection and mount that file as a virtual drive. Once the drive mounted you can see all your private files inside just like a regular hard disk. TrueCrypt also can be used to protect your USB or Flash disks. Bare in mind TrueCrypt is designed for advanced users. Here are the main features of TrueCrypt.
- 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.
