Rust for Ethical Hackers – Build a Custom Shellcode Encryption Tool! using AES-GCM & XOR 🔥

⚠️ DISCLAIMER: This video is for EDUCATIONAL and ETHICAL SECURITY RESEARCH purposes only. The content demonstrates encrypting shellcode concepts and adversary simulations in a controlled environment to help defenders build better detection strategies. Unauthorized use of these techniques is illegal. In this module, we bridge the gap between low-level security tradecraft and high-level Rust engineering. We build a production-grade CLI tool that automates the encryption and decryption of shellcode, moving from basic XOR to authenticated AES-256-GCM encryption. The goal of this project is twofold: understanding why modern EDRs signature simple XOR loops and mastering the advanced Rust patterns required to build a modular, memory-safe security tool. Part 1: Advanced Rust Engineering We don't just write code; we architect a system. This project serves as a deep dive into: Abstraction with Traits & Dynamic Dispatch: Using Box dyn Trait to switch encryption engines at runtime. The Type System: Leveraging Enums and Unit Structs to represent different cryptographic strategies. Functional Programming: Using Iterators and the Map function for memory-efficient data transformations. Metaprogramming: Using Derive Macros (Debug, Clone, Copy, PartialEq) to reduce boilerplate. Error Handling: Using map_err to lift low-level library errors into readable CLI output. Part 2: Security & Cryptography We apply these Rust concepts to solve real-world security challenges: XOR Obfuscation: Implementing bitwise transformation and discussing why it fails against heuristic EDR analysis. AES-GCM Authenticated Encryption: Why Integrity matters. We explore how the Authentication Tag prevents shellcode tampering. CLI Development: Building a functional interface to ingest raw .bin payloads and output encrypted buffers. Memory Lifecycle: Preparing encrypted payloads for safe decryption in a loader environment. Key Implementation Details: Implementing the Encryptor Trait. Handling the Nonce and Tag in AES-GCM. Using std::io for robust terminal I/O (Flush, Read, Write). Target Audience: This video is for developers who want to see Rust's high-level abstractions applied to low-level security problems, Red Teamers and Security Engineers who are interested in Rust programming
