CrabCrypt is a secure file encryption tool with GUI, designed for effortlessly encrypting and decrypting any file. With AES encryption and a sleek Tkinter interface, CrabCrypt ensures your files remain confidential and protected from unauthorized access.
🚀 Features
✅ Secure Encryption - Uses AES-256 encryption with strong key derivation.
✅ Authenticated Encryption - Utilizes AES-GCM for encryption, eliminating the need for padding and preventing common attacks.
✅ Strong Key Derivation - Offers both PBKDF2 (600K iterations) and Argon2 for enhanced security.
✅ No Padding Issues - Since AES-GCM is used, padding vulnerabilities (like those in CBC) are completely avoided.
✅ Intuitive UI - Simple and user-friendly interface for file selection and password protection.
✅ Multi-File Support - Encrypt and decrypt any type of file.
✅ Offline & Private - No internet connection required, ensuring complete privacy.

🐧 For manual Installation or for Linux & macOS Users
1️⃣ Clone the Repository
git clone https://github.com/spyboy-productions/CrabCrypt.git
cd CrabCrypt
2️⃣ Install Dependencies
pip install -r requirements.txt
3️⃣ Run CrabCrypt
python CrabCrypt.py
🔑 How to Use
- Select a file: Click on the file selection area to browse your files.
- Enter a password: Choose a strong password for encryption.
- Encrypt or Decrypt: Click the respective button to process the file.
- Save the output: The encrypted/decrypted file will be saved with a prompt.
⚠️ Limitations
🚧 No Password Recovery - If you forget the password, decryption is impossible.
🚧 File Size - Large files may take longer to process.
TO Do
- Self-Destruct Mode Have a mode where if a trigger is met (e.g., a password attempt fails multiple times), all selected files get encrypted and shredded instantly.
- Post-quantum encryption algorithm Example: Kyber + AES-GCM (Kyber is a quantum-resistant algorithm from NIST’s PQC finalists) use post-quantum KEMs (Kyber, FrodoKEM) to encrypt the AES key

Structured screenshot analysis for UI implementation and critique. Analyzes every UI screenshot with a 5×5 spatial grid, full element inventory, and design system extraction — facts and taste together, every time. Escalates to full implementation blueprint when building. Trigger on any digital interface image file (png, jpg, gif, webp — websites, apps, dashboards, mockups, wireframes) or commands like 'analyse this screenshot,' 'rebuild this,' 'match this design,' 'clone this.' Skip for non-UI images (photos, memes, charts) unless the user explicitly wants to build a UI from them. Does NOT trigger on HTML source code, CSS, SVGs, or any code pasted as text.
