Truecrypt 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: Hidden volume (steganography – more information may be found here). No TrueCrypt volume can be identified (volumes cannot be distinguished from random data). Encryption algorithms: AES-256, Serpent, and Twofish. Mode of operation: XTS.

Right-click integration with Windows Explorer makes AxCrypt the easiest way to encrypt individual files in Windows. Double-click integration makes it as easy to open, edit and save encrypted files as it is to work with unencrypted files. Many additional features, but no configuration required, just install it and use it. AxCrypt encrypts files that are safely and easily sent to other users via e-mail or any other means. Self-decrypting files are also supported, removing the need to install AxCrypt to decrypt.

SiFEU is a program that lets you encrypt files with strong Blowfish encryption and SHA-1 for calculating the hash sum of the password. The interface allows you to add one or multiple files to encrypt and you can also use it from the right-click menu in Windows Explorer. The encrypted files will have an additional .SiFEU extension and require SiFEU to be installed in order to open/decrypt them. |

more free encryption
FreeOTFE is an open source OTFE (on the fly disk encryption) software for Windows. It presumably creates encrypted partitions (the documentation does not explicitly state this, nor does it state if it supports the creation of encrypted container files). You mount the encrypted volume under Windows and it appears as a drive which you can use normally. FreeOTFE supports "hidden volumes" which are encrypted volumes that are created inside another encrypted volume. All FreeOTFE volumes also have no identifiable signature. It is compatible with Linux losetup, which is useful if you need to use your encrypted volumes in both Linux and Windows. Supported ciphers include AES and Twofish, and supported hash algorithms include MD2, MD4, MD5, RIPEMD-128, RIPEMD-160, SHA-1, SHA-224, SHA-256, SHA-384, SHA-512. At the time I write this review, FreeOTFE is still in BETA testing.
This encryption software will encrypt your entire hard disk (including your operating system) using a "fast AES algorithm". It also supports the encryption of floppy disks, memory sticks and other removable devices. Even your Windows hibernation file is stored encrypted on the disk.
Scramdisk 4 Linux is a suite of Linux tools that allow you to create and access Scramdisk and TrueCrypt containers. It has a Linux driver that allows you to mount such containers. Scramdisk for Windows and TrueCrypt are free on-the-fly disk encryption software that you can find elsewhere on this page.
Cryptainer LE allows you to create 25 MB encrypted containers that appear to Windows as disk drives. It supports Windows 95 (OSR 2), 98, ME, 2000, XP and 2003. It uses the Blowfish algorithm. It apparently also allows you to send encrypted emails as well.
CryptoExpert Lite is a free on the fly encryption program that creates a virtual disk on your disk from a container file. It supports the CAST encryption algorithm.
Working with documents on your computer where you don't want prying eyes to see? You can get free software that sets up a drive on your hard disk where all files saved will be encrypted. The drive need not be an actual hard disk or partition, it can be a file that is set up to look like a drive to Windows for transparent operation. It is easy to use, free, freely redistributable with the full source code available. It works on all Windows systems. Supported encryption include DES, IDEA, Triple-DES, Blowfish, and CAST. If you find yourself continually encrypting individual files on your computer, this might prove to be the easier to use solution. Note: E4M is no longer being maintained. The link above leads to a third party site.
Scramdisk allows you to create an encrypted virtual drive on your Windows systems where you can store files which will be automatically encrypted. The drive acts like a normal drive which you can access just like any other disk drive on your system. Supported encryption algorithms include Triple DES (EDE), Blowfish, DES, IDEA, MISTY1, Square, and TEA (both 16 and 32 rounds). This software is no longer supported.
Free Public Key Encryption Software
- Windows Privacy Tools (WinPT)
-
Windows Privacy Tools (including the Windows Privacy Tray, ie WinPT Tray, and the WinPT Explorer Extensions), is a set of tools that allow you to encrypt your data using GnuPG (see elsewhere on this page). It is a frontend to GnuPG that resides in your system tray that may be used as a universal plug-in to any email software. The software is free.
- PGP (Pretty Good Privacy) Public Key Encryption
-
The above link is to the International PGP Home Page, where you can get free binaries and sources for Pretty Good Privacy (PGP) for a variety of operating systems for either US or non-US countries. You can use PGP to encrypt your email in conjunction with your email client, be it Eudora, ELM, PINE, or whatever. PGP is a public key encryption system, which means that you have two keys (passwords), one which is known only to you and the other is known to your recipient. Messages or documents (or whatever) encoded with one key can only be decoded with the other. You can read more about this from the PGP FAQs at the site.
- GPG: GNU Privacy Guard
-
GPG, a.k.a. GnuPG, is the GNU version of PGP (Pretty Good Privacy), a public key encryption system. Like all things GNU, it is free and can be freely distributed and modified. It is generally compatible with the newer PGP versions (depending on the encryption algorithms you choose); but you should read their FAQ for more details.
Free Encryption Software with Steganography
- S-Tools
-
S-Tools is an encryption software with steganographic capabilities. It hides files in BMP, GIF and WAV files after compressing and encrypting them. It runs on Windows and supports drag and drop. It uses the facilities provided in a freely available encryption library cryptlib (which supports a host of well known encryption algorithms like AES, Blowfish, etc) to perform its encryption.
- 4t HIT Mail Privacy Lite
-
This encryption software allows you to hide your private data such as email messages inside an image (JPG, GIF, TIFF, BMP, etc). The image is still viewable as an image, but it also contains the encrypted version of your secret message (steganography). The website does not specify which encryption algorithm is used.
- Camouflage
-
This encryption software performs steganographic functions as well. It encrypts your file using an unspecified algorithm (in fact the website merely says it scrambles your data) and attaches them in another file of your choice, such as sound files, picture files, etc. I suspect that this software is only for the casual user (who merely wants to hide files from a prying brother or sister) and not for anyone who really needs strong encryption (such as governmental agencies, banks, companies, and the like).
