If you deploy .NET assemblies to your client machines, some kind of decompilation will always be possible using reflector and similar tools. However, this situation isn’t materially different to what you’d encounter if you wrote the application in native C++. It is always possible to decompile things – if it were impossible, the processor couldn’t … Read more
Command line decompilation for JD-GUI is a highly requested feature but it’s not implemented yet. Perhaps you can use the following workaround in the meantime: jar (or zip) all the classes you want decompiled together. Launch JD-GUI and open your jar (zip) archive. Use “File” – “Save JAR Sources” menu option. It will decompile all … Read more
See How do I decompile Java class files? There’s a link there to JD-GUI, which seems to be about what you’re looking for. Edit: Also see Open Java *.Class Files. Edit 2: And Best free Java .class viewer?, which specifically mentions .NET Reflector.
This might be impossible or at least very hard. The DLL’s contents don’t depend (a lot) on it being written in C++; it’s all machine code. That code might have been optimized so a lot of information that was present in the original source code is simply gone. That said, here is one article that … Read more
Since most of the parts of .NET is open-sourced, ILSpy also works with Linux and Mac. From project GitHub page: Decompiler Frontends Aside from the WPF UI ILSpy (downloadable via Releases, see also plugins), the following other frontends are available: Visual Studio 2017/2019 extension marketplace Visual Studio Code Extension repository | marketplace ICSharpCode.Decompiler NuGet for … Read more
Most x86 instructions (other than some specialized instructions such as movsb) can only access one memory location. Therefore a move from memory to memory requires going through a register with two mov instructions. The mov instruction can be used in the following ways: mov mem, reg mov reg, mem mov reg, reg mov reg, imm … Read more
You can follow these steps to modify your java class: Decompile the .class file as you have done and save it as .java Create a project in Eclipse with that java file, the original JAR as library, and all its dependencies Change the .java and compile Get the modified .class file and put it again … Read more
If it executes, it can be decompiled. Objective-C is particularly easy to decompile into readable code thanks to its dynamic features. If you want to make things a little bit harder, you could write most of your code in plain C and strip the executable — which of course has the tradeoff of making your … Read more
For the final, compiled code of your application, the short answer is “no”. Different tools are able to extract different information from the code (e.g. the forms setups) and there are P code decompilers (see Edgar’s excellent link for such tools). However, up to this day, there is no decompiler for native code. I’m not … Read more
Because Java byte-code is closer (more similar) to the source than assembly. In particular, .class files include metadata for classnames, method names, field & parameter types, etc… All a Java (or .Net) decompiler needs to do is look at the instructions in each method body, and turn them into the appropriate syntactic constructs. By contrast, … Read more
