Stego-Conceal

A proof of concept for concealing a file within a carrier image

Features

The Stego-Conceal tool allows for a user to take a carrier image and embed a file within it with little to no noticeable difference in image quality for the carrier image

Features include:

• Embed many different file types within the carrier image
• the carrier image is BMP format
• Encrypt the data if desired with a password

Installation

Be sure to download the proper requirements located in the requirements.txt file

pip install -r requirements.txt

Prerequisites

• Python 2.7+

Usage

The Stego-Conceal app comes with basic help switch statement that willassist you with all the parameters you can specify:

usage: conceal.py [-h] [-i INPUT] [-o OUTPUT] [-f FILE] [-p PASSWORD] [-v]
                  {encode,decode}
                  
A steganography tool to conceal a file within an image.

positional arguments:
  {encode,decode}                   Supply the operation you want to perform on the image
  
optional arguments:
  -h, --help                        show this help message and exit
  -i INPUT, --input INPUT
                                    The carrier image to hold the concealed data
  -o OUTPUT, --output OUTPUT        The filename to output the combined files as
  -f FILE, --file FILE              The file to store in the carrier image
  -p PASSWORD, --password PASSWORD  Encrypt the embedded file with a password
  -v, --verbose                     Increase verbosity level 

To encode a carrier image with a secret file, use the encode parameter with an input file, secret file, and output file name:

python conceal.py encode -i <path_to_carrier_file> -f <path_to_secret_file> -o <output_file>

To decode a carrier image, use the decode paramter with the -i flag to specify the carrier image to input with the secret_file embedded, and the output file path:

python conceal.py decode -i <path_to_carrier_file> -o <output_file>

You can optionally specify a password with the encode parameter to encrypt the secret file embedded in the carrier image.

python conceal.py encode -i <path_to_carrier_file> -f <path_to_secret_file> -o <output_file> -p test123
python conceal.py decode -i <path_to_carrier_file> -o <output_file> -p test123

To increase verbosity, simply increase the number of v's to the -v flag

-v for ERROR
-vv for WARNING
-vvv for INFO
-vvvv for DEBUG
