# 🛡️ SafePixel – Image Encryption using AES

Secure your images with **SafePixel**, a Flask-based web application that encrypts and decrypts images using the **Advanced Encryption Standard (AES)** algorithm. SafePixel ensures **data confidentiality and integrity** by combining AES encryption with **SHA-256 hashing** for verification.

[View Repository](https://github.com/Prathamesh5152/SafePixel---Image-Encryption-using-AES)

## 🚀 Features

- AES-based encryption and decryption for images (`.jpg`, `.jpeg`, `.png`)
- Generates a secure random 16-character AES key for each encryption
- Verifies file integrity using SHA-256 hashing
- Easy-to-use web interface built with Flask
- Download encrypted and decrypted files directly from the browser

## ⚙️ Installation

1. **Clone the Repository**
```bash
git clone https://github.com/Prathamesh5152/SafePixel---Image-Encryption-using-AES.git
cd SafePixel---Image-Encryption-using-AES

2. Create a Virtual Environment

python -m venv venv
venv\Scripts\activate     # Windows
source venv/bin/activate  # Linux/Mac

3. Install Dependencies

pip install -r requirements.txt

4. Run the Application

python app.py

Open your browser and navigate to: http://127.0.0.1:5000/

🔐 How It Works

Encryption

1. Upload an image.
2. A 16-character AES key is generated.
3. Image bytes are padded and encrypted using AES.
4. SHA-256 hash of the original data is appended for integrity check.
5. Encrypted image is saved in the encrypted/ folder.

Decryption

1. Upload the encrypted image and enter the AES key.
2. File is decrypted and verified with SHA-256 hash.
3. If valid, the decrypted image is saved in the uploads/ folder.

⚠️ Security Notes

• Keep your AES key safe — it is required to decrypt the image.
• AES encryption ensures high security and performance.
• SHA-256 ensures the image is not tampered with during storage or transfer.
• For production, consider proper key management solutions.
