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 (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. Not all functionalities of Stegano are covered.

Requirements

• Python 3;

• Pillow;

• piexif.
