decompiling

We are planning to develop a client server application using C# and MySQL. We plan to sell the product on the shelf like any other software utility. We are worried about the decompilation of our product which does have some sort of edge over our competitors in terms of usability and bundled functionality. How can we prevent our software from decompilation, so the business logic of the product remains intact? We have heard about Reflector and other decompilers which makes our code very much vulnerable for copying. Our customer base is not Corporates but medical practitioners who themselves may

Can you recommend a Java decompiler for Eclipse? My other questions is what restrictions is there for using a decompiled code from an other Java program? Illegal or what? I dont know much about licenses. Thanks for reading. Mirek Pluta I'd suggest the one that pops up on google, which is the JD Java decompiler. It works really nice. As for the restrictions, you'd have to read a license of particular software, there might be written that any way of decompilation is forbidden. Thorbjørn Ravn Andersen I like JadClipse - but it shows its age in places. You will need: a jad binary jadClipse

I know, many similar questions has been asked here. I am not asking if I can protect my compiled Java class - because obviously you will say 'no you can't'. I am asking what is the best known method of protecting Java classes against de-compiling? If you aware of any research or academic paper in this field please do let me know. Also if you have used some methods or software please share you experience? Any kind of information will be very useful. Thank you. First if you're targeting "only" the Windows market there's a very easy to prevent the ".class to .java" decompilation: use a tool like

As we know , there are a lot of java decompiler tools which can convert .class to .java file. Therefore,we need to protect our .java files against decompiler. I know this is a big topic,and maybe there is no ending. Usually, there are two ways : obfuscator and customized classloader. Is there any mature solution or open source framework, which combined those two ways ? Another aspect is related with exe4j, which package jars to exe file,seems like it can protect java codes , because what we can see is exe file instead of jars or class files. But indeed, when it runs, it decompose all jars

I am really having trouble finding a good working Lua bytecode decompiler. I'm trying to decompile some scripting files I found in a game but they appear to be compiled, yet don't seem impossible to decode. What's the best tool to decompile Lua binaries? It looks like LuaDec itself was last updated for Lua 5.0.2. A new version targeting Lua 5.1.x bytecode has been released as LuaDec51 . The wiki is always a good place to start looking for resources as mentioned by f3lix. The mailing list is also a good place to ask. Do note that it is relatively easy to add obfuscation or even encryption to
