Presentation
|
|
============
|
|
|
|
Stegano_ is 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.
|
|
|
|
Stegano implements these methods of hiding:
|
|
|
|
- using the red portion of a pixel to hide ASCII messages;
|
|
- using the `Least Significant Bit <http://en.wikipedia.org/wiki/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 and TIFF).
|
|
|
|
Moreover some methods of steganalysis_ are provided:
|
|
|
|
- steganalysis of LSB encoding in color images;
|
|
- statistical steganalysis.
|
|
|
|
You can also use Stegano through a `Web service <https://github.com/cedricbonhomme/stegano-web>`_.
|
|
Not all functionalities of Stegano are covered.
