Presentation

Stéganô 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 Stéganô only hide messages, without encryption. Steganography is often used with cryptography.

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 and TIFF).

Moreover some methods of steganalysis are provided:

• steganalysis of LSB encoding in color images;
• statistical steganalysis.

Requirements

• Python 3;
• Pillow;
• piexif.
