# Secure Image Steganography with AES Encryption 🔒
[](https://www.python.org/)
[](https://streamlit.io/)
[](https://opencv.org/)
A secure data hiding system that combines AES-256 encryption with LSB steganography to protect sensitive information during transmission.
## Features ✨
- **Military-grade Encryption** 🔐
- AES-256-CBC with PBKDF2 key derivation
- Secure password hashing with 100,000 iterations
- Random salt and IV generation
- **Advanced Steganography** 🖼️
- LSB (Least Significant Bit) embedding
- Automatic capacity calculation
- Header-based length encoding
- Multi-image format support (PNG, JPG, JPEG)
- **User-friendly Interface** 💻
- Streamlit-based web UI
- Drag-and-drop functionality
- Real-time feedback
- Cross-platform compatibility
## Installation ⚙️
1. Clone the repository:
```bash
git clone https://github.com/x0lg0n/AICTE-INTERNSHIP-PROJETC.git
cd AICTE-INTERNSHIP-PROJECT
```
## Install dependencies:
```bash
pip install -r requirements.txt
```
## Usage 🚀
Start the application:
```bash
streamlit run app.py
```
## Encoding Process:
- Upload cover image
- Enter secret message
- Set encryption password
- Download protected image
## Encoding Demo
## Decoding Process:
- Upload protected image
- Enter decryption password
- View extracted message
## Decoding Demo
