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.
