CryptVault

CryptVault is a secure, high-performance file encryption and decryption web application featuring an immersive cyberpunk-themed UI. Built with a React frontend and a FastAPI backend, it uses military-grade AES encryption to ensure your files stay completely secure.

Features

• AES-CBC Encryption: Industry-standard encryption using the Python cryptography library.
• PBKDF2 Key Derivation: Securely derives AES keys from your provided password with 100,000 iterations to prevent brute-force attacks.
• Cyberpunk "Neural" UI: An immersive, terminal-style interface complete with dynamic animations, glowing elements, and real-time telemetry logs.
• Vercel Optimized: Ready for full-stack deployment on Vercel with a pre-configured vercel.json for routing serverless functions and static assets.
• Format Agnostic: Safely encrypt and decrypt any file format or size.

Tech Stack

Frontend:

• React 19
• Vite
• Tailwind CSS v4
• Vercel Web Analytics

Backend:

• Python 3
• FastAPI
• Cryptography (Hazmat primitives)

Running Locally

1. Clone the repository

git clone https://github.com/abhishek-2006/File-Encryption-Decryption-System.git
cd File-Encryption-Decryption-System

2. Start the Backend

Navigate to the backend directory, install the dependencies, and run the FastAPI server:

cd backend
python -m venv venv
# On Windows: venv\Scripts\activate
# On Mac/Linux: source venv/bin/activate
pip install -r requirements.txt
uvicorn main:app --reload

The backend will run on http://localhost:8000.

3. Start the Frontend

In a new terminal window, navigate to the frontend directory, install the dependencies, and start the Vite dev server:

cd frontend
npm install
npm run dev

The frontend will typically run on http://localhost:5173.

How It Works

1. Ingestion: Upload the file you wish to secure (or decrypt). The system automatically detects .enc extensions to switch modes.
2. Identity: Enter your secret password (private key).
3. Release: The system streams the file to the backend, encrypts/decrypts the bitstream in memory, and instantly returns the processed file to your local machine.

Security Warning

This tool encrypts files entirely based on the password you provide. If you lose or forget your password, there is absolutely no way to recover your encrypted files. Always keep your passwords stored safely in a password manager.
