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.
