CrabCrypt🦀🔐

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.

🚀 Download & Installation

🖥️ For Windows Users

📥 Download CrabCrypt.exe and run it – No installation required!

🔹 Steps to run:

1. Click the download link above.
2. Double-click CrabCrypt.exe.
3. Windows SmartScreen Warning? ⚠️
   • If you see a SmartScreen warning, click "More info" and then "Run anyway".
   • This happens because the app is new and unsigned, but it's safe!

pip install pyinstaller
pyinstaller --onefile --noconsole --icon=crabcrypt.ico CrabCrypt.py
  

🐧 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

1. Select a file: Click on the file selection area to browse your files.
2. Enter a password: Choose a strong password for encryption.
3. Encrypt or Decrypt: Click the respective button to process the file.
4. 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

1. 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.
2. 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
