Stegano 0.9.7
Posted Oct 28, 2019
Authored by Cedric Bonhomme | Site github.com

Stegano is a basic Python Steganography module. Stegano implements two methods of hiding: using the red portion of a pixel to hide ASCII messages, and using the Least Significant Bit (LSB) technique. It is possible to use a more advanced LSB method based on integers sets. The sets (Sieve of Eratosthenes, Fermat, Carmichael numbers, etc.) are used to select the pixels used to hide the information.

Changes: Fixed markdown of the previous release.

Changes: The generator provided to the functions lsbset.hide() and lsbset.reveal() is now a function. This is more convenient for a user who wants to use a custom generator (not in the module lsbset.generators). Performance improvements for the lsb and lsbset modules.
