cryptosteganography's Introduction

Cryptosteganography

A python steganography module to store messages or files protected with AES-256 encryption inside an image.

Steganography is the art of concealing information within different types of media objects such as images or audio files, in such a way that no one, apart from the sender and intended recipient, suspects the existence of the message. By default steganography is a type of security through obscurity.

Additionally this module also enhance the security of the steganography through data encryption. The data concealed is encrypted using AES 256 encryption, a popular algorithm used in symmetric key cryptography.

Prerequisites

Python 3+

pip3

(Most Linux systems comes with python 3 installed by default).

Dependencies Installation (Ubuntu)

$ sudo apt-get install python3-pip

Dependencies Installation (MacOS)

To install Python3 I recommend use Homebrew package manager

The script will explain what changes it will make and prompt you before the installation begins.

$ ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

Edit your ~/.profile to include (if it is not already there)

export PATH=/usr/local/bin:/usr/local/sbin:$PATH

To install Python 3:

$ brew install python3

Installation

To install the package just run

$ pip3 install cryptosteganography

Usage

Use as a library in a python program

Store a message string inside an image

from cryptosteganography import CryptoSteganography

crypto_steganography = CryptoSteganography('My secret password key')

# Save the encrypted file inside the image
crypto_steganography.hide('input_image_name.jpg', 'output_image_file.png', 'My secret message')

secret = crypto_steganography.retrieve('output_image_file.png')

print(secret)
# My secret message

Store a binary file inside an image

Note: This only works if the concealed file size is smaller than the input image

from cryptosteganography import CryptoSteganography

message = None
with open('sample.mp3', "rb") as f:
    message = f.read()

crypto_steganography = CryptoSteganography('My secret password key')

# Save the encrypted file inside the image
crypto_steganography.hide('input_image_name.jpg', 'output_image_file.png', message)

# Retrieve the file ( the previous crypto_steganography instance could be used but I instantiate a brand new object
# with the same password key just to demonstrate that can it can be used to decrypt)
crypto_steganography = CryptoSteganography('My secret password key')
decrypted_bin = crypto_steganography.retrieve('output_image_file.png')

# Save the data to a new file
with open('decrypted_sample.mp3', 'wb') as f:
    f.write(secret_bin)

Use as a python program

Check help at command line prompt to learn how to use it.

                        Output for the binary secret file (Text or any binary
                        file).

Save message example

$ cryptosteganography save -i 4824157.png -m "My secret message..." -o output.png

Version 0.8.3
Ubuntu 22.04

Installing problem on MacBookPro4,1 Catalina 10.15.7 (dosdude1 patched)

I tried a few times to install while manually installing Pillow and also updating my homebrew installation, but install cryptosteganography always stops installing where the first problematic part seems to be that one:

Building wheels for collected packages: pillow

Could it be that my version of Pillow is to new? Should I maybe change the requirements.txt, but when using the default installation method I can’t change the sources, or? (Sorry, I’m quite the newbie in regards to the vast Python universe ;-)

In the past I also had a few issues with installing Python3 and some other dependencies when installing via homebrew. I think it was cause of homebrew expecting at least: nehalem processor architecture and this machine (MacBookPro4,1) still only has a Penryn processor. I could work around this problem with making two changes to the hardware.rb file (replacing "nehalem" with "core2") and reinstalling/compiling some dependencies from source, not using the bottled versions.

the full error messages output log reads:

robo@mbx ~ % pip3 install cryptosteganography
DEPRECATION: Configuring installation scheme with distutils config files is deprecated and will no longer work in the near future. If you are using a Homebrew or Linuxbrew Python, please see discussion at https://github.com/Homebrew/homebrew-core/issues/76621

Decrypting a photo of the encrypted image

Suppose we hide some information in an image and print it.
Is this library suitable to retrieve the hidden information from a photo of the printed image captured by a smartphone camera?

I assume printing and taking a picture would distort the lower bit information.
The photo will also contain background and extraneous pixels, which would require finding out the outline of the relevant image.

Retreive method not working

Following the example in README seems to work, but consistently returns None with the retreive() method.
