Decompilers
A decompiler is a computer program that translates an executable file back into high-level source code. Unlike a compiler, which converts high-level code into machine code, a decompiler performs the reverse process. While disassemblers translate executables into assembly language, decompilers go a step further by reconstructing the disassembly into higher-level languages like C. Due to the one-way nature of the compilation process, decompilers usually cannot perfectly recreate the original source code. They often produce obfuscated and less readable code. Introduction Decompilation is the process of transforming executable code into a high-level, human-readable format using a decompiler. This process is commonly used for tasks that involve reverse-engineering the logic behind executable code, such as recovering lost or unavailable source code. Decompilers face inherent challenges due to the loss of critical information during the compilation process, such as variable names, c ...

Obfuscation (software)
In software development, obfuscation is the practice of creating source code, source or machine code that is intentionally difficult for humans or computers to understand. Similar to obfuscation in natural language, code obfuscation may involve using unnecessarily roundabout ways to write statements. Programmers often obfuscate code to conceal its purpose, logic, or embedded values. The primary reasons for doing so are to prevent Anti-tamper software, tampering, deter reverse engineering, or to create a puzzle or recreational challenge to deobfuscate the code, a challenge often included in Crackme, crackmes. While obfuscation can be done manually, it is more commonly performed using Executable compression, obfuscators. Overview The architecture and characteristics of some languages may make them easier to obfuscate than others. C (programming language), C, C++, and the Perl programming language are some examples of languages easy to obfuscate. Haskell (programming language), Hask ...
