>>All,

>>We've had a few threads over at Foxite looking at VFP protection schemes. This week a protected app was cracked to source in minutes; previously Leonid Lepin was able to lift a key out of three other protection products with no trouble at all.
>>
>>Having taken a particular interest I'd suggest that few protection schemes out there can protect a VFP app for more than a few minutes.
>>
>>Anybody is welcome to post a sample of their preferred protection scheme to see whether anybody can crack it. Please use a free dbf as that saves a lot of time to prove the point.
>>
>>The most effective protection scheme I can find comes from here: http://www.baiyujia.com/f_download.asp ,download VFP Compiler demo. The download includes English instructions. Basically the product splits a VFP project into a VFP exe with no useful content and a C++ dll containing heavily obfuscated, decomposed and distorted instructions that are fearfully difficult to piece back into a VFP project, unlike most other schemes from which it is easy to extract a complete VFP project.
>>
>>If I'm wrong I'd be delighted if somebody would show me- I'd rather go back to the drawing board than cruise along believing my work is protected when it's wide open.
>>
>>FWIW, here is the entire source I can extract from one of my own VFP compiler apps: as you can see, I don't need to waste time trying to prevent somebody grabbing this because it's not useful: a hacker now needs to disassemble the associated dll or at least trap a plethora of VFP runtime calls hoping to splice something useful out if it.
