Stegano 0.11.4
Posted Sep 9, 2024
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: Added a parameter, close_file, to lsb.reveal in order to specify if the file must be closed at the end of the processing.
