Publisher's description of TrueCrypt
From TrueCrypt Foundation:Protect your sensitive data with this free open-source disk encryption software. Creates a virtual encrypted disk within a file and mount it as a real disk. Encrypt an entire hard disk partition or a device, such as USB flash drive. Automatically and transparently encrypt in real time.
TrueCrypt provides two levels of plausible deniability, in case an adversary forces you to reveal the password: a hidden volume (steganography- more information may be found here); no TrueCrypt volume can be identified (volumes cannot be distinguished from random data). TrueCrypt uses encryption algorithms AES-256, Blowfish (448-bit key), CAST5, Serpent, Triple DES, and Twofish. It is based on Encryption for the Masses (E4M) 2.02a, conceived in 1997.
Version 6.2 includes the I/O pipeline now uses read-ahead buffering, which improves read performance especially on solid-state drives, typically by 30-50%.

Editor's review of TrueCrypt
stars
- "Ssshhh"
- Reviewed on: November 7, 2008
- Version reviewed: TrueCrypt 6.2
The ultimate freeware encryption program, TrueCrypt is loaded with powerful features that those concerned with protecting their data from thievery should want--and have.
It offers 11 algorithms for encrypting your private files in a password-protected volume. You can store your encrypted data in files (containers) or partitions (devices). TrueCrypt works hard to offer powerful data protection, recommending complex passwords, explaining the benefits of hidden volumes, and erasing telltale signs of the encryption process, including mouse movements and keystrokes. Though the interface may not be immediately intuitive, its powerful, on-the-fly encryption for no cost still earns the freeware security tool a top rating.
The useful tips in the extensive help manual and volume-creation wizard provide excellent guidance. In fact, they're required reading, as TrueCrypt lacks any considerable in-program help. For instance, the tutorial explains the entire concept beyond "hidden" volumes, but it doesn't quite explain how to mount them. One obvious downside of any strong encryption program is if you happen to forget your lengthy, secure password, you should consider any protected files as good as gone. However, once files are mounted to a local drive with your password or key, they conveniently behave just like any normal files, allowing you to easily open, copy, delete, or other modify them another way. Dismount the volume, and voila--your previously accessible files are now safely secure from prying eyes.
Users can even create a hidden operating system, encrypted away from nosy busybodies, but make no mistake--TrueCrypt is not for the casual encryption explorer. Be sure to thoroughly understand what you're doing with the program before you do something regrettable.

"Failed to get this program working on my computer"

Summary: Failed to get this program working on my computer

Version: TrueCrypt 6.2
"An absolute requirement for my situation"
Pros: I take my laptop with me to work and back home every day and on business trips almost every week. I store my personal and business date in crypts. I consider encryption of such data an absolute requirement and TrueCrypt is the only answer for me
Cons: TtrueCrypt can't handle NTFS compressed files. Does not inform you if you have mistakenly created a compressed crypt file until it completes the file, which can take minutes to hours. This failure is the only reason TrueCrupt down't get 5 stars
Summary: An absolute must for anybody who wants to keep their data secure on a Windows machine. Just be careful to create uncompressed crypts

":) Best free encryption program!!!"
Pros: 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.

Summary: More pro:
Encryption is automatic, real-time (on-the-fly) and transparent.

Version: TrueCrypt 6.2
"Great for encrypting files en-masse"
Pros: Fairly easy to understand assuming you know basic terminology for filesystems as you are not just encrypting individual files, but placing files into a "container filesystem" which becomes a file on your hard drive.
Cons: Does not do single file encrypting. If they had this as an option I would have given it 5 stars. The utility assumes (probably rightfully so) that the user will need many files encrypted so does not provide quick single file encryption ability.
Summary: Great if you have a lot of files to encrypt all at once. Works smooth and has the option to not stick around running when no encrypted containers are mounted, keeping invasiveness and CPU overhead to a minimum. Not so great if you only have a few f... read more >>
