You can adapt this file completely to your liking, but it should at least

contain the root `toctree` directive.

Welcome to Stéganô's documentation!

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.
|
|
|
|
The advantage of steganography, over cryptography alone, is that messages do not attract
|
|
attention to themselves. If you are interested in cryptography have a look at my project pySecret.

|
Requirements
|
|
============
|
|
|
|
- Python (2.4 -> 2.7);
|
|
- Python Imaging Library (PIL).
|
|
|
|
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.
