Hide secret data within a digital image using good ol' terminal

Installation

The recommended way for installing this package is using, python PIP, package installer for python and git, the stupid content tracker. Linux users can install them using sudo apt install python3-pip git. After installing pip run this command,

pip install git+https://github.com/GuptaAyush19/pystego.git

Users can also install this manually by downloading the zip file from here, extracting it and running this command inside the project directory,

python setup.py install

Usage

Upon installation and packages all setup, the package can now directly execute using the command given below. Note that this is os independent which means it can run on both linux and windows.

# encode using message as an argument (not recommended as this will be saved in your terminal history)
pystego -e -s 
   
     -m 'hello there'
# decode
pystego -d s

Flags and arguments:

  1. -e => flag to encode the file
  2. -d => flag to decode the file
  3. -s => path to the image file, also referred to as source/src

Example

The following shows an example of encoding and decoding a message using -e, -d and -s flag only. Enter the message once the prompt ENTER MESSAGE: is visible.

Encoding

$ pystego -es resources/hacker.png
INFO:root:ENCODING `resources/hacker.png`
ENTER MESSAGE: this is something else
DEBUG:PIL.PngImagePlugin:STREAM b'IHDR' 16 13
DEBUG:PIL.PngImagePlugin:STREAM b'IDAT' 41 65536
SUCCESS: Image Encoded Successfully @ resources/hacker.png

Decoding

$ pystego -ds resources/hacker.png
INFO:root:DECODING `resources/hacker.png`
DEBUG:PIL.PngImagePlugin:STREAM b'IHDR' 16 13
DEBUG:PIL.PngImagePlugin:STREAM b'IDAT' 41 65536
SUCCESS: Image Decoded Successfully @ resources/hacker.png
→ this is something else

TODO

  • Implement file encoding into digital images
  • Save the output message into another standalone file
  • Implement encryption of the original text for better security
  • Documentation for pystego module
