`Stegano <https://github.com/cedricbonhomme/Stegano>`_, a pure Python
|
|
Steganography module.
|
|
|
|
Steganography is the art and science of writing hidden messages in such a way
|
|
that no one, apart from the sender and intended recipient, suspects the
|
|
existence of the message, a form of security through obscurity. Consequently,
|
|
functions provided by Stegano only hide messages, without encryption.
|
|
Steganography is often used with cryptography.
|
|
|
|
Installation
|
|
------------
|
|
|
|
.. code:: bash
|
|
|
|
$ pipenv install Stegano
|
|
✨🐍✨
|
|
|
|
You will be able to use Stegano in your Python programs.
|
|
|
|
If you only want to install Stegano as a command line tool:
|
|
|
|
.. code:: bash
|
|
|
|
$ pipsi install Stegano
|
|
✨🍰✨
|
|
|
|
pipsi installs scripts (system wide available) provided by Python packages into
|
|
separate virtualenvs to shield them from your system and each other.
|
|
|
|
|
|
Usage
|
|
-----
|
|
|
|
A `tutorial <https://stegano.readthedocs.io>`_ is available.
|
|
|
|
|
|
Use Stegano as a library in your Python program
|
|
'''''''''''''''''''''''''''''''''''''''''''''''
|
|
|
|
If you want to use Stegano in your Python program you just have to import the
|
|
appropriate steganography technique. For example:
|
|
|
|
.. code:: python
|
|
|
|
>>> from stegano import lsb
|
|
>>> secret = lsb.hide("./tests/sample-files/Lenna.png", "Hello World")
|
|
>>> secret.save("./Lenna-secret.png")
|
|
>>>
|
|
>>> clear_message = lsb.reveal("./Lenna-secret.png")
|
|
|
|
|
|
Use Stegano as a command line tool
|
|
''''''''''''''''''''''''''''''''''
|
|
|
|
Hide and reveal a message
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
.. code:: bash
|
|
|
|
$ stegano-lsb hide -i ./tests/sample-files/Lenna.png -m "Secret Message" -o Lena1.png
|
|
$ stegano-lsb reveal -i Lena1.png
|
|
Secret Message
|
|
|
|
|
|
Hide the message with the Sieve of Eratosthenes
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
.. code:: bash
|
|
|
|
$ stegano-lsb-set hide -i ./tests/sample-files/Lenna.png -m 'Secret Message' --generator eratosthenes -o Lena2.png
|
|
|
|
The message will be scattered in the picture, following a set described by the
|
|
Sieve of Eratosthenes. Other sets are available. You can also use your own
|
|
generators.
|
|
|
|
This will make a steganalysis more complicated.
|
|
|
|
|
|
Running the tests
|
|
-----------------
|
|
|
|
.. code:: bash
|
|
|
|
$ python -m unittest discover -v
|
|
|
|
Running the static type checker:
|
|
|
|
.. code:: bash
|
|
|
|
$ python tools/run_mypy.py
|
|
|

Contributions
|
|
-------------
|
|
|
|
Contributions are welcome. If you want to contribute to Stegano I highly
|
|
recommend you to install it in a Python virtual environment with pipenv.
