🔐 Secret Message Encryptor

---

🌟 "Bridging Classical Cryptography with LLM-Powered Cryptanalysis"

Built by Rahul Raj Jaiswal, an aspiring software developer passionate about AI integration, full-stack architecture, and building intelligent solutions to real-world problems.

---

🚀 Core Features

• 🛠️ Custom Encryption: Combines character swapping with an AI-generated substitution map and shift cipher.
• 🤖 AI Decrypt Assistant: Integrates with the Groq API (Llama 3.1) to attempt heuristic cryptanalysis on encrypted strings.
• 💾 Key Management: Automatically handles encryption keys and character mapping via secret_key.json.
• 📱 QR Integration: Built-in capability to handle encrypted data via QR codes (under development).
• 🎨 Modern GUI: A clean, interactive experience powered by tkinter and Pillow.

💡 Why This Project Matters

"Securing data through custom algorithmic ciphers while exploring the frontiers of AI-driven cryptanalysis."

In an era of ubiquitous AI, this project demonstrates:

• AI Integration: Real-world usage of High-inference LLMs for complex pattern recognition.
• Document Intelligence: Leveraging AI to solve problems where traditional keys are missing.
• Engineering Rigor: Clean separation of concerns between crypto logic, UI, and AI layers.
