Stegano by Cédric Bonhomme is a pure Python Steganography module for PNG files

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
