You can adapt this file completely to your liking, but it should at least contain the root `toctree` directive. Welcome to Stéganô's documentation! =================================== Presentation ============ .. figure:: https://api.travis-ci.org/cedricbonhomme/Stegano.svg?branch=master :align: left :target: https://travis-ci.org/cedricbonhomme/Stegano Stéganô_ is a 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 Stéganô only hide message, without encryption. Indeed steganography is often used with cryptography. Requirements ============ - Python_ >= 3.2 (tested with Python 3.3.1); - `Pillow`_. Methods of hiding ================= For the moment, Stéganô implements these methods of hiding: - using the red portion of a pixel to hide ASCII messages; - using the `Least Significant Bit `_ (LSB) technique; - using the LSB technique with sets based on generators (Sieve for Eratosthenes, Fermat, Mersenne numbers, etc.); - using the description field of the image (JPEG). Moreover some methods of steganalysis_ are provided: - steganalysis of LSB encoding in color images; - statistical steganalysis.
