Project Description

Stéganô

Stéganô, a pure Python Steganography module.

Installation

$ sudo pip install Stegano

You will be able to use Stéganô in your Python programs or as a command line tool.

Usage

A tutorial is available.

Use Stéganô as a library in your Python program

If you want to use Stéganô in your Python program you just have to import the appropriate steganography technique. For example:

>>> from stegano import lsb
>>> secret = lsb.hide("./tests/sample-files/Lenna.png", "Hello World")
>>> secret.save("./Lenna-secret.png")

Use Stéganô as a program

Hide a message
$ lsb hide -i ./tests/sample-files/Lenna.png -m "Secret Message" -o Lena1.png
Hide the message with the Sieve of Eratosthenes
$ 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

$ python -m unittest discover -v

Release History

0.6.7 (2017-02-21)

  • bugfix: added missing a dependency in the setup.py file.

0.6.6 (2017-02-20)

  • improved docstrings for the desciption of the generators;
  • improved the command which displays the list of generators.

0.6.5 (2017-02-16)

  • added a command to list all available generators for the lsb-set module;
  • test when the data image is coming via byte stream, for the lsb module.

0.6.4 (2017-02-06)

  • a command line for the ‘red’ module has been added;
  • bugfix: fixed a bug in the lsb-set command line when the generator wasn’t specified by the user.

0.6.3 (2017-01-29)

  • Support for transparent PNG images has been added (lsb and lsbset modules).

0.6.2 (2017-01-19)

  • bugfix: solved a bug when the image data is coming via byte streams (ByteIO), for the exifHeader hiding method.

0.6.1 (2016-08-25)

  • reorganization of the steganalysis sub-module.

0.6 (2016-08-04)

  • improvements of the command line of Stéganô. The use of Stéganô through the command line has slightly changed (‘hide’ and ‘reveal’ are now sub-parameters of the command line). No changes if you use Stéganô as a module in your software. The documentation has been updated accordingly.

0.5.5 (2016-08-03)

  • bugfix: Incorrect padding size in base642string in tools.base642binary().

0.5.4 (2016-05-22)

  • the generator provided to the functions lsbset.hide() and lsbset.reveal() is now a function. This is more convenient for a user who wants to use a custom generator (not in the module lsbset.generators).
  • performance improvements for the lsb and lsbset modules.

0.5.3 (2016-05-19)

  • reorganization of all modules. No impact for the users of Stegano.

0.5.2 (2016-05-18)

  • improvements and bug fixes for the exifHeader module;
  • added unit tests for the exifHeader module;
  • improvements of the documentation.

0.5.1 (2016-04-16)

  • minor improvements and bug fixes;
  • added unit tests for the slsb and slsbset modules.

0.5 (2016-03-18)

  • management of greyscale images.

0.4.6 (2016-03-12)

  • bugfix when the length of the message to hide is not divisible by 3, for the slsb and slsbset module.

0.4.5 (2015-12-23)

  • bugfix.

0.4.4 (2015-12-23)

  • new project home page;
  • minor updated to the documentation.

0.4.3 (2015-10-06)

  • bug fixes for Python 3;
  • bug fixes in the scripts in ./bin.

0.4.2 (2015-10-05)

  • first stable release on PypI.

0.4 (2012-01-02)

This release introduces a more advanced LSB (Least Significant Bit) method based on integers sets. The sets generated with Python generators (Sieve of Eratosthenes, Fermat, Carmichael numbers, etc.) are used to select the pixels used to hide the information. You can use these new methods in your Python codes as a Python module or as a program in your scripts.

0.3 (2011-04-15)

  • you can now use Stéganô as a library in your Python program; (python setup.py install) or as a ‘program’ thanks to the scripts provided in the bin directory;
  • new documentation (reStructuredText) comes with Stéganô.

0.2 (2011-03-24)

  • this release introduces some bugfixes and a major speed improvement of the reveal function for the LSB method. Moreover it is now possible to hide a binary file (ogg, executable, etc.);
  • a new technique for hiding/revealing a message in a JPEG picture by using the description field of the image is provided.
