[Buildroot] [PATCH 3/3] package/python-stegano : new package

[Jugurtha BELKALEM]

Steganography is the art and science of writing hidden
messages in such a way that no one , apart from the sender
and intended recipient , suspects the existence of the message,
a form of security through obscurity.
Steganography is often used with cryptography.

More about python-stegano is available at :
https://pypi.org/project/stegano/.

Stegano can be tested :
$ python3
>>> from stegano import lsb
>>> secret = lsb.hide("./image.png", "Hello World")
>>> secret.save("./image-with-steganography.png")
To get back text :
>>> clear_message = lsb.reveal("./image-with-steganography")
