StegaNet

StegaNet is a steganography implementation written in C, combined with socket programming for secure message transmission. It supports hiding and exchanging text, images, and audio messages. If no media is provided, the system can generate random images or audio automatically. Audio can also be imported directly from YouTube links.

Features

• Send normal messages over sockets
• Image Steganography (Encode & Decode)
• Audio Steganography (Encode & Decode)
• Download audio directly from YouTube

How to run

1. Clone the repo

git clone git@github.com:IshaanNene/StegaNet.git

2. Install dependencies

For Linux:

make install-deps

For macOS:

make install-deps-mac

Additionally, install Node.js dependencies (for YouTube audio download):

npm install

3. Run the project

1. Start two terminals Run make clean && make all && make run on one then wait, then run make run on the other terminal
2. Make sure one is set to client mode and the other in server mode, and also ensure they both are on the same port
