Data-Protection-using-Steganography-and-Cryptography

Welcome to the Steganography and Cryptography Portal! This application allows you to hide text in audio files, text in images, and images within images using steganographic techniques.

Features

• Text in Audio: Hide text messages within audio files.
• Text in Image: Hide text messages within image files.
• Image in Image: Hide one image within another image.

Prerequisites

• Python 3.x
• Required Python libraries: stegano, Pillow, twofish, memory_profiler, wave

Installation

To get started, clone this repository and install the necessary dependencies:

git clone https://github.com/pranjalgautam11/Data-Protection-using-Steganography-and-Cryptography.git
pip install -r requirements.txt

Usage

Run the main script to access the Steganography and Cryptography Portal:

python menudriven.py

You will be presented with a menu to choose from different steganographic techniques:

Welcome to Steganography and Cryptography Portal
Enter 1: text in audio
Enter 2: text in image
Enter 3: image in image
Enter 0: Exit
Choice:

Options

1. Text in Audio: Enter 1 to hide text within an audio file. This will invoke the aud_steg() function from the textinaudio module.
2. Text in Image: Enter 2 to hide text within an image file. This will invoke the incript() function from the textinimage module.
3. Image in Image: Enter 3 to hide one image within another image. This will invoke the image_steg() function from the imageinimage module.
4. Exit: Enter 0 to exit the portal.

Modules

textinaudio.py

Provides functions to encode and decode text messages in audio files using the LSB (Least Significant Bit) technique. Also supports encryption and decryption of the encoded audio files.

textinimage.py

Provides functions to encode and decode text messages in image files by modifying pixel values. Also supports encryption and decryption of the encoded image files.

imageinimage.py

Provides functions to encode and decode images within other images using the LSB technique. Also supports encryption and decryption of the encoded image files.
