Stéganô is a basic Python Steganography module. It uses the Python Imaging Library (PIL). Stéganô implements two methods of hiding: using the red portion of a pixel to hide ASCII messages, and using the Least Significant Bit (LSB) technique.

Version 0.4 of Stéganô is coming with a new LSB method which uses sets in order to select the pixels where the message will be hidden. For the moment sets can be generated with the Sieve of Eratosthenes, Fermat numbers and Syracuse numbers.

Release Notes: 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.
Release Notes: 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. Moreover, new documentation (reStructuredText) comes with Stéganô.
Release Notes: 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.
