Quick Answer: Is It Legal To Decompile Code?

Can you reverse engineer compiled code?

9 Answers.

You can never get back to the exact same source since there is no meta-data about that saved with the compiled code.

But you can re-create code out from the assembly-code..

How do I debug without source code?

Native Java Bytecode Debugging without Source CodeInstall the Java SE JDK. … Install Eclipse. … Install Bytecode Visualizer. … Load the JAR to be Analyzed. … Open the JAR’s Code with Bytecode Visualizer. … Set Breakpoints. … Debugging the Disassembled Code.

What is reverse engineering example?

Hardware reverse engineering involves taking apart a device to see how it works. For example, if a processor manufacturer wants to see how a competitor’s processor works, they can purchase a competitor’s processor, disassemble it, and then make a processor similar to it.

Is it possible to decompile code?

A decompiler is a computer program that takes an executable file as input, and attempts to create a high level source file which can be recompiled successfully. Decompilers are usually unable to perfectly reconstruct the original source code, and as such, will frequently produce obfuscated code. …

Can you decompile C++?

Yes, but none of them will manage to produce readable enough code to worth the effort. You will spend more time trying to read the decompiled source with assembler blocks inside, than rewriting your old app from scratch. I haven’t seen any decompilers that generate C++ code. … Google for “decompiler”.

Is it possible to decompile an EXE?

Yes, you can decompile the .exe file and get the source code in three ways as I know (and maybe possible in other ways too 🙂 ) Telerik’s JustDecompile . … NET Decompiler: Decompile Any . NET Code .

4 Answers. Decompiling is absolutely LEGAL, regardless of what the shills say. At most, you can be sued for unauthorized activity relating to software unless you’re redistributing it. … There is absolutely NO law in the U.S. that states you cannot copy for private purposes or decompile software.

What are the 3 stages of reverse engineering?

This process has three main stages:Implementation recovery. Quickly learn about the application and prepare an initial model.Design recovery. Undo the mechanics of the database structure and resolve foreign key references.Analysis recovery. Remove design artifacts and eliminate any errors in the model.

Is reverse engineering software illegal?

Reverse engineering generally doesn’t violate trade secret law because it is a fair and independent means of learning information, not a misappropriation. Once the information is discovered in a fair and honest way, it also can be reported without violating trade secret law.

Can we convert .exe to source code?

Yes, easily. Anyone can decompile a . NET assembly and get source code which can be compiled again into the same assembly.

How do I run an EXE file in Visual Studio?

In Visual Studio you can open any EXE as a ‘project’. Just go to File->Open->Project/Solution and browse to the .exe file. Like you would if it was a .

Can reverse engineering be used for service?

3D Reverse Engineering Services​ Reverse Engineering involves taking existing physical parts and assemblies and creating CAD models and detailed toleranced drawings. … Tools and dies can even be generated by using the surface models created by our 3D reverse engineering services.

There is no provision for decompilation (white-box reverse engineering) in UK copyright law, and no fair use defense if the reverse engineering is for commercial research or study. … However, sniffing (black-box reverse engineering) for interoperability purposes is allowed.

What language is EXE written in?

.exe files are executable files in windows. They are created by compilers which converts the source code in to machine code. This also explains why they are faster compared to python (interpreted language) which gets compiled to machine code as the program is running .

Can you decompile a DLL?

If it’s the older Visual Basic (pre-. NET), then the DLL is compiled as what’s called p-code and there are a few options for doing some variations on decompiling. … Such a DLL is compiled to machine language and can only be directly decompiled to assembly language.

Is reverse engineering easy?

Reverse engineering in itself is a broad task – the difficulty highly depends on the product. The only common is that successfully reverse engineering a product typically requires domain knowledge. Whether it be manufacturing, a process, software, or other.

Why is reverse engineering illegal?

Because reverse engineering can be used to reconstruct source code, it walks a fine line in intellectual property law. Many software license agreements strictly forbid reverse engineering. … Patching software to defeat copy protection or digital rights management schemes is illegal.

What can you reverse engineer?

Reverse engineering can be used when a system is required to interface to another system and how both systems would negotiate is to be established. Such requirements typically exist for interoperability. Military or commercial espionage.

Can you decompile third party code to remove bug?

I see this question is still driving traffic to my blog, so I’ll add an answer: yes, debugging 3rd-party assemblies is now possible with the JetBrains dotPeek decompiler (completely free), by using it as a Symbol server.
