What does code obfuscation achieve?

Code obfuscation primarily makes the source code difficult to decipher, which is why this choice is the correct answer. This technique is used to protect intellectual property and prevent unauthorized access to sensitive algorithms or business logic by transforming readable code into a version that is much harder for humans to understand. This can help in safeguarding against reverse engineering, as attackers may find it challenging to make sense of the obfuscated code.

While improving code performance, enhancing code readability, or reducing code size may be objectives in other areas of software development, they are not the main goals of code obfuscation. In fact, obfuscation often introduces additional complexity, which can sometimes lead to a decrease in performance and readability. Therefore, the primary role of code obfuscation is indeed to obscure the logic and flow of the code from potential attackers or malicious actors.
