# Secure Image Steganography App
This is a simple Streamlit app that allows you to encode secret messages into images using LSB (Least Significant Bit) steganography and decode hidden messages from images.
## Features
- **Encode Message:**
- Upload an image.
- Enter your secret message.
- The app encodes the message into the image and provides a download link for the modified image.
- **Decode Message:**
- Upload an image with a hidden message.
- The app decodes and displays the secret message.
## Directory Structure

```
## Setup and Installation
1. **Clone the Repository:**
```bash
git clone
cd steganography_app
```
2. **Create a Virtual Environment (optional but recommended):**
```bash
python -m venv venv
source venv/bin/activate # On macOS/Linux
venv\Scripts\activate # On Windows
```
3. **Install Dependencies:**
```bash
pip install -r requirements.txt
```
4. **Run the Streamlit App:**
```bash
streamlit run app.py
```
## Usage
- Navigate to the **Encode Message** or **Decode Message** section from the sidebar.
- Follow the on-screen instructions to upload images and encode or decode messages.

### `images/` Folder
Place your sample images (e.g., `sample_input.png` and optionally `encoded_sample.png`) in this folder. These images are used for testing and demonstration purposes.
---
### `saved_images/` Folder
This folder is intended for storing user-uploaded or processed images if needed. It can remain empty initially.
