rust_code_obfuscator_core

Core engine for the Rustfuscator — a control flow and syntax obfuscation tool for Rust codebases.

🧠 What is rust_code_obfuscator_core?

This crate is the core logic behind Rustfuscator, a Rust code obfuscation tool that transforms readable Rust code into functionally equivalent but harder-to-analyze and harder-to-reverse-engineer output (but not impossible !!).

It is not a standalone crate — it powers the procedural macros and CLI-level abstractions of the Rustfuscator project.

Note about Key management for crypto.rs

Now uses build-time key management, the key is injected via build.rs:

• If OBFUSCATOR_KEY_HEX (64 hex chars) is set, that value is used.
• Otherwise, a random 32-byte key is generated for the build.

A 256-bit AES key is provided at build time (not in source code).

• Deterministic builds:

  export OBFUSCATOR_KEY_HEX="00112233... (64 hex chars) ..."
  cargo build --release 
  

• If unset, a random key is generated per build.
• The runtime API returns Result (no unwrap() in crypto paths).
