TrueCrypt is a cross-platform software for on-the-fly encryption for hard drives, meaning that the data can be encrypted and decrypted automatically before being saved and without any involvement from the user. The drive volume wouldn’t appear readable when encrypted until being decrypted with the encryption password.

TrueCrypt GUI

This software can be very helpful for the people looking for a free but powerful tool to encrypt and secure their data especially on a notebook using its 11 algorithms. The users must be sure not to forget their password because there is no way to get their protected files back. When the drive is mounted with the correct password, the protected partition/drive would appear and behave as any normal partition, but when its dismounted, the drive becomes secure and inaccessible.

Trucrypt Encryption Algorithms

TrueCrypt can perform the following tasks:

  • Creates a virtual encrypted disk within a file and mounts it as a real disk.
  • Encrypts an entire partition or storage device such as a USB flash drive or a hard drive.
  • Encrypts a partition or drive where Windows is installed (pre-boot authentication).
  • Encryption is automatic, real-time (on-the-fly) and transparent.
  • Parallelization and pipelining allow data to be read and written as fast as if the drive was not encrypted.
  • Encryption can be hardware-accelerated on modern processors.
  • Provides plausible deniability, in case an adversary forces you to reveal the password:
  • Hidden volume (steganography) and hidden operating system.
  • Encryption is automatic, real-time (on-the-fly) and transparent.

All of these features comes at absolutely no cost, better, you can also obtain the source code. Download TrueCrypt for Windows, Linux or Mac OS X from Here
