SecureStego 🔒🎥🖼️🎵

SecureStego is a robust and user-friendly steganography suite that allows you to securely embed and extract secret messages within video, image, and audio files.
It employs AES-GCM encryption for confidentiality and offers both a Command-Line Interface (CLI) and a Graphical User Interface (GUI) for ease of use.

Features ✨

• Multi-Media Support: Hide/extract messages in
  • .wav audio files
  • .png, .bmp image files
  • .mp4, .avi, .mkv video files
• Strong Encryption: Uses PBKDF2HMAC + AES-GCM for secure password-based encryption.
• Command-Line Interface (CLI): Scriptable and automation-friendly.
• Graphical User Interface (GUI): Built with Streamlit, intuitive for all users.
• Least Significant Bit (LSB) Steganography: Embeds data by modifying the least significant bits of media content.
• Technologies used: Python, Streamlit, OpenCV, PyDub, NumPy

How It Works ⚙️

1. Encryption: Secret message is encrypted with a user-provided password.
2. Conversion: Encrypted data converted to binary + delimiter 1111111111111110.
3. Embedding: Binary string hidden inside media’s least significant bits (pixels for images/videos, samples for audio).
4. Extraction: Reverse process to reconstruct and decrypt the hidden message.

Installation 🛠️

Prerequisites

• Python 3.x

Setup

1. Clone the repository:

git clone https://github.com/DevPatel1106/SecureStego.git
cd SecureStego

2. Install dependencies:

pip install -r requirements.txt

Usage 🚀

1. Command-Line Interface (CLI) a. Embed a message:

python stego_cli.py embed --input <input_file> --output <output_file> --message <secret_message> --password <your_password>

• Example:

python stego_cli.py embed --input cover_image.png --output stego_image.png --message "This is a secret message" --password mypassword123

b. Extract a message:

python stego_cli.py extract --input <stego_file> --password <your_password>

• Example:

python stego_cli.py extract --input stego_image.png --password mypassword123

2. Graphical User Interface (GUI)

• Run the Streamlit app:

streamlit run stego_gui.py

This will open a browser window where you can interact with the application.
