WWF-VFP A tool to avoid VFP decompilations 1.0.0.8
Jorge Grundman, E.U.I.T. Telecom.
WWF-VFP is a free tool to avoid VFP decompilations. Every serious developer knows the existence of commercial tools available on the market which are able to reproduce the original source code from a codified compiled Microsoft Visual FoxPro application. Due the nature of Microsoft Visual FoxPro engine until now there was not possible to avoid the decompilation. WWF-VFP is a tool born to protect the Microsoft Visual FoxPro EXE applications from decompilation. This version fix the need to copy the file to be protected to WWF-VFP folder. NOTE: You will need Microsoft Visual Basic SP5 Runtime files to run this app.

Description
For the moment, this is the pre-release of the tool, so I need feedback from the users to develop a better way to protect VFP's EXE files. Inside you will find recomendations to get the better results. Jorge Grundman http://mp3.com/grundman I'm sorry to tell you that if your read the license and installation instructions which it shows just you run the installer, appears that is a pre-release and warning you about: "...For the moment, this application is on pre-release. In short will be completely published. What does it mean? Whenever you launch the protected application the original file (the VFP EXE file) will be recreated in the app directory. In this way you can compare if you can decompile the protected file vs the original one...." Also, if you follow the thread (in Universal Thread) about this program you will find not only the previous comments but the things about I'm workig. The idea always was to see if someone can decompilate the protected file. You say this can be easily used by others to decompress: well... that is what I want. This is the challenge. The original file always need to be launched due Microsoft Visual FoxPro needs to parse the instructions, but there is more than a way to avoid someone can terminate the program. Of course, any application can be dissasembled with tools that trace even the OS. But the idea is create as many difficulties as can be do it. In other words, do not need to branding anything. Why I don't upload the version which avoid the EXE file to be created? Because Iprior to do them, I wish the application can be tested to correct it. For last, I'm collecting feedback from users about it to when the final version will be launched, has many features the users request. For the moment, there is no packing utility for VFP apps. Think about that. What if the packing has a protection scheme build inside?. What about if the password of this protection is the file inside and not a phrase?. What about if the application is decompressed on memory? What about if the loader is a service which continuosly looks if the application is running? What about if the loader don't let you use Ctrl+Alt+Del? What about if the loader is a invisible service installed at startup so if the user shutdown the PC at starts waste the physical space of the application?. This is what is coming: only difficulties to refox the application. Please, with the next release and other applications read the instructions and comments to avoid you to discover by yourself what is described. Thanks anyway for trying WWF-VFP

Is it possible to include the AUNZIP32.DLL in the resulting EXE, and also to not require the VB runtime? Yes, I know that the EXE will became bigger, but distributing only one exe is sometimes better. Zlatin Zlatev, November 11, 2003
