Below are some of our favorite freeware / open-source software utilities:-
TrueCrypt - Free Open-Source Disk Encryption Software
Free open-source disk encryption software for Windows XP/2000/2003 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, Blowfish (448-bit key), CAST5, Serpent, Triple DES, and Twofish.
Mode of operation: LRW (CBC supported as legacy).

AxCrypt
AxCrypt is a powerful, yet extremely easy to use file encryption program. It integrates directly with Windows Explorer, enabling encryption, decryption, viewing and editing of any file with just a few clicks of the mouse. AxCrypt uses the AES-128 and SHA-1 algorithms, which comply with US Government and Internet standards. Additional features include creation of self-decrypting files, automatic re-encryption after editing, secure deletion (wiping) of files and temporaries, cryptographic data integrity validation, separate key and data encrypting keys, secure internal memory handler and more. AxCrypt uses a straight forward one-click way to process files. There is no extra interface to configure or open, other than selecting/entering your password.

GPGshell
GPGshell is a graphical interface for GnuPG (GNU Privacy Guard). It requires an already working installation of GnuPG v1.4.x (v1.4.6 or later), because it does not have any cryptographic code itself, and some basic knowledge about the GnuPG command-lines and functions.
