In the realm of software development, code obfuscation is a crucial technique used to protect source code from unauthorized viewing and modification.
“obfusgator.zig” leverages the Zig programming language to provide a robust tool for developers seeking to obfuscate their Zig projects effectively.
This article delves into how “obfusgator.zig” works and demonstrates its usage on various Zig applications.
