Code obfuscation is a vital technique in software security, specifically designed to defend against unauthorized reverse-engineering and tampering.
It is a form of protection that makes it significantly harder for attackers to understand, modify, or steal the functionality of the software.

The core functions of any effective software protection strategy include three key components: detecting unauthorized attempts to break into or reverse-engineer the software, actively preventing these attacks, and modifying the software in such a way that, if the protection is bypassed, the software's functionality degrades in an inconspicuous manner, ensuring that the attack goes unnoticed.

Skater .NET Obfuscator is an advanced free tool for defending against reverse-engineering attempts. It achieves this by employing several techniques aimed at rendering the disassembled code incomprehensible to unauthorized users. Specifically, it focuses on obfuscating assembly member names, making them meaningless or ambiguous, thereby preventing attackers from easily understanding the software's structure. Additionally, it encrypts string literals to further obscure the data that could be useful for reverse-engineers. Finally, Skater .NET Obfuscator incorporates "trick" commands in the code that make it difficult or impossible for decompilers to reconstruct the original, functional code from the disassembled version, preventing recompilation of the software. These techniques combine to significantly raise the complexity of reverse-engineering efforts, making it more costly and time-consuming for potential attackers.
