Safe is around for more than 6 years now. Back in 2001 I started working on
Safe during my summer semester break. My intention was to play around with
Java 2 Micro Edition (J2ME) and to solve the problem of remembering so many
different passwords and logins. It started pretty basic but over the years
Safe improved much and a few month ago a desktop application called
SafeDesktop joined Safe. These two applications are a mature solution to
organize and store sensitive data (such as passwords and logins) in an
encrypted way. To keep the data between the desktop and the mobile device
up-to-date a easy to use synchronization mechanism is provided.

In 2007, Safe is downloaded from the project website more than 17900 times.
Since its appearance in May 2007, the download counter for SafeDesktop shows
currently a value around 2500. On average, I get at least one email every
week regarding Safe or SafeDesktop. The forum is also used quite frequently
by users to discuss different topics around Safe and SafeDesktop.
Additionally, there is a small community of people which write about Safe and
SafeDesktop in their blogs and forums. As far as I know at least four
comprehensive user reviews have been published and an unknown number of posts
mentioned Safe or SafeDesktop.

Although, the source code is freely available under GPL, I only received a
patch once. And by that time the problem has already been solved by myself.
Frankly, I am a bit disappointed that it is so hard to find developers that
are willing to contribute to the project. This means, all the development
work has been carried out by myself. This is one of the main reasons why I
decided to fork Safe and SafeDesktop into pay software.

During the last weeks two friends of mine and I worked pretty hard to get Safe
and SafeDesktop ready for sale. First, we renamed Safe to MobileKnox and
SafeDesktop to DesktopKnox. Second, I added a bunch of new features. The
security algorithms used by MobileKnox and DesktopKnox were overhauled. Now,
both applications use the well-known AES encryption standard with a key
length of 256 Bit for encryption. SHA256 and SHA512 are used for one-way
hashes. Furthermore, the import and export functionality of both applications
are improved. An IP address finder tool is added to DesktopKnox. For this, I
used JSTUN, another project I am working on. MobileKnox contains now a
version checker to make it easy for users to stick with the latest version.
Third, we set up a fancy website to promote the applications and to support

For the near future, we plan features like categories and synchronization over
Bluetooth. However, the appearance of new features depends on the number of
buyers we will have in the next few weeks.

We provide a trail version of MobileKnox that is able to store three entries.
To store unlimited numbers of entries a personalized serial key must be
bought. The price tag for such a key is 9.50Eur. It can be obtained from the

So, I really want to thank everybody who contributed to Safe and SafeDesktop.
Thanks for all the nice emails and the delighting discussions! I hope all
Safe and SafeDesktop users will switch to MobileKnox and DesktopKnox. ;-)

Best regards,
