⚡ Overview

Magic Bytes is a client-side web application designed to analyze file headers (hex signatures) to identify the true format of a file, regardless of its file extension. This tool is essential for security researchers, developers, and forensic analysts to detect Extension Spoofing (e.g., an .exe disguised as a .jpg) and analyze raw Base64 data safely.

Built with a Privacy-First approach, all processing happens locally in your browser. No files are uploaded to any server.

✨ Key Features

🛡️ Forensic Analysis & Security

• True File Type Detection: Identifies files by their "Magic Bytes" (file signatures) rather than trusting the operating system's file extension.
• Spoofing Alert System: Automatically detects and warns if a file's extension does not match its internal signature (e.g., malware.pdf containing executable headers).
• Risk Assessment: Categorizes files into High, Medium, or Low security risks based on their executable potential.
• Base64 Decoder: Capable of analyzing raw Base64 strings directly to determine the encoded file type.

🎨 UI & Experience

• Cyber-Aesthetic Design: Features a "GitHub Dark Mode" inspired interface with smooth, cinematic CSS animations.
• Responsive & Adaptive: Fully responsive layout with a built-in Dark/Light theme toggle.
• Multi-Language Support: Full localization support for English, Azerbaijani, and Russian.
• Instant Preview: Generates safe previews for supported image formats.

🛠️ Technical Stack

• Core: HTML5, CSS3, Vanilla JavaScript (ES6+)
• Styling: CSS Variables, Flexbox/Grid, Keyframe Animations.
• Logic: FileReader API for hex extraction, ArrayBuffers for byte manipulation.
• Icons: Scalable Vector Graphics (SVG).
