List of best C decompilers

Many of us find it difficult to get the list of best Decompilers for C. That’s the reason I crafted this post to gather some amazing c decompilers for you.

As a programmer, one of the trickiest tasks that can make you scratch your head is to rewrite a code from one language to the other language simpler. To get this task done, we have a quite easier way of decompiling the codes through a Decompiler. 

Some of the easiest languages to understand by the programmers are the C language. So, we usually think of decompiling a trickier code into C language code to understand it well. 

C decompilers

Here we will talk about some of the best C decompilers that will let you decompile your codes into C language and make analysis easier for you. Let’s dig into the article to learn about C decompilers.

Ghidra

Ghidra is an open-source decompiling software created by the National Security Agency of the U.S. It allows the users to analyze its compiled code on Windows, macOS, and Linux. 

It has a collection of high-end software analysis tools for disassembly, graphing, assembly, scripting, binary analysis, and decompilation. It is an advanced IDE written in Java, having a user interface similar to the Eclipse IDE. It supports many processors and executable formats. 

Users can also create their plug-ins or scripts in either Java or Python. It can analyze malicious codes and generate deep insights into vulnerabilities in networks and systems. In short, it has set an excellent standard for being a decompiler specifically for C language.

Here is the link to download Ghidra. 

Reko

Reko is reverse engineering software used to decompile codes into C language. It usually accepts machine code, binaries and decompiles them into C. It only runs on Windows. It consists of a front-end window, a Decompiler engine, and a back-end processing. 

It can also be used from the command line. The decompiler receives input as an executable file of binaries. Then it analyzes the input binaries and formats the output on screen using the decompilation process.

Snowman

The snowman is a promising Decompiler that accepts the native code, usually in binary, and decompiles it into the C language. It supports x86 and x86-64 architecture. It only runs on Windows. 

It reads ELF and PE file formats only. It can be used as a GUI application to navigate assembler and output codes. It can also be used as an IDA plug-in and easily integrated into IDA’s GUI. It enjoys all executable file formats supported by IDA when used as an IDA plug-in. As a command-line tool, it is used for batch processing.

RetDec

RetDec is a retargetable Decompiler for C developed by the Brno University of Technology, Czech Republic. It supports x86, ARM, MIPS, PIC32, x86-64, and ARM64 architectures. It accepts multiple file formats, i.e., ELF, PE, Mach-O, COFF, AR, Intel HEX, and raw machine code. 

It can statically analyze the executable files. Its salient features include detecting the packer, removing statically linked library code, identifying and debugging the faulty information, and integrated disassembler. Its key output language is C.

Boomerang 

The boomerang is an open-source and retargetable C Decompiler for machine code. It runs on Windows and Linux. 

They can resolve high-level and tricky problems during decompiling a code. The quality of the output code often varies. The output code is structured by having local variables, types, and functions, whereas the functions are disturbed by the number of variables and their use in the code.

C decompiler

C decompiler allows us to decompile the high-level source codes into more readable C source codes. 

It is a very suitable application for beginners to experiment with decompiling. Its GUI is organized in a very structured manner. Regarding its usage, you just have to browse and load the input file and then press the decompile button to proceed. 

The processing time depends upon the size of the file. The decompiled code will be displayed in the main window of the application. 

REC Studio 4

REC Studio 4 is the latest version of the original decompiler REC. It is a C decompiler that runs on Windows, macOS, and Linux. It can read multiple files designed differently and compiled on different operating systems. It has a partial single static assignment analysis technique. 

Moreover, it supports 32 and 64-bit binaries. It accepts the raw code or files of any format in Windows, macOS, and Linux and generates a C-like code. The output is mainly based on the C language, but some parts are not recognized, so it needs improvement in its successive versions. 

Hex Rays

Hex-Rays is a C decompiler plug-in of IDA Pro, which runs on Windows, Linux, and macOS. It is merged with the run-time debugging and disassembly skills of IDA, which makes it the best C decompiler. 

It runs on x86, x64, ARM32, ARM64, PowerPC, PowerPC64, MIPS, and MIPS64. It converts the executable programs into the C language code, which can analyze the potential threats of programs. It is also used for software validation and code coverage analysis.

Final Words

I hope you have learned about decompiling into C through the above-mentioned decompilers. Using these compilers can help convert your complex code into any easy C-version code that the program analysts can easily analyze.
