Midwest Research Corporations' KetuFile is an ultra lightweight piece of encryption software that employs advanced AES encryption that will encrypt using algorithms up to 512-bit. It allows the user to encrypt any file on a Windows PC up to 2GB in size and supports integration with email clients such as Outlook and Eudora.
The small (5.9MB) setup file installs in less than a minute. All functions are straight forward and intuitive, and using the software should prove effortless for the novice user. Configuration is simple and provided in a no nonsense, simple interface. There should be no confusion when using any feature of this program.
KetuFile offers 512-bit key encryption lengths, which is more than adequate for securing critical information. There is no option for shredding the source files and the originals remain intact after conversion. Data integrity is maintained when using the application, but this is irrelevant, considering the originals are never destroyed.
KetuFile’s encryption software performs quickly when converting files, if you consider that it takes less than 2 seconds to encrypt a 100kb file. In addition, a password of only 1 character is permitted during processing (trial version only). Context menu options are not supported, so attempting to perform right click operations will not work. KetuFile is compatible with Windows 98, NT 4.0 SP6a, 2000, and XP. This encryption software will run on later versions of Windows 95 that have long file support. The software will also install and run in Linux using the utility WINE.
Documentation consists of a mini help button. When clicked, it reveals a plain text file in notepad. Pressing the master help button opens an internet browser with an HTML document with lots of links, text and some graphics. Despite the minimalistic nature of the documentation, it is sufficient. Support on the website has email links, phone/fax numbers and a company mailing address.
Midwest Research Corporations' KetuFile is a small data encryption software utility that works quickly on small files, but could not be verified on large files due to the limited trial version. The software is supposedly tailored to the defense industry, but it has no wiping capabilities for secure erasure, nor a virtual keyboard for password input. Only the most casual of computer users will be satisfied with the limited data protection the software provides. We can recommend KetuFile for emailing sensitive documents to others, but in order to decrypt a file, each user would need a license for the software, which happens to be the priciest of all the encryption utilities we reviewed.
The software provides strong encryption algorithms without draining system resources.
KetuFile doesn’t offer high level security features for data wiping or circumventing surveillance software.
For the average user, KetuFile provides hassle-free data protection without a large amount of hands-on maintenance.
