Steganography is the practice of hiding a secret message inside of (or even on top of) something that is not secret. That something can be just about anything you want. These days, many examples of steganography involve embedding a secret piece of text inside of a picture. Or hiding a secret message or script inside of a Word or Excel document.
The purpose of steganography is to conceal and deceive. It is a form of covert communication and can involve the use of any medium to hide messages. It’s not a form of cryptography, because it doesn’t involve scrambling data or using a key. Instead, it is a form of data hiding and can be executed in clever ways. Where cryptography is a science that largely enables privacy, steganography is a practice that enables secrecy – and deceit.
To setting up environment to run this script use this bash command:
pip install -r requirements.txtUsage: python3 stego.py { inject [options] | extract [options] } -f <picture-file-path>
There are two modes to use this simple application:
1. inject - Allows to inject passed string message to stego-container. There are
following additional needed options:
-m <message-string> [-o <output-key-file-path>]
2. extract - Allows to extract string message from stego-container. Just pass key
file path: -k <key-file-path>
For mode details for each other modes enter '--help'.
