[Buildroot] [PATCH 0/3] package/python-stegano

[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.
Steganography is often used with cryptography.

Python-stegano allows to apply steganography
easily on images and retrive hidden messages
that were injected.

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

Steganography is the art and science of writing hidden

a form of security through obscurity.
Steganography is often used with cryptography.

More about python-stegano is available at :

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")

Looking at the code, I didn't really see where pillow is mandatory.
Apparently, you can pass images opened to pillow, but you don't have
to. So I dropped this "select". Of course, if that's incorrect, let me
know, and we can fix it.

This description (from their github) is not super useful, I've instead
taken the description from their documentation, which is a bit more
sensible.

This hash was incorrect and didn't match the actual license file.

I fixed those issues, and applied. Thanks!

Not a strict requirement, but since you have a simple test case, what
about adding a runtime test in support/testing/ ?

Could you give more details about the dependency on those 3 libraries?
Is it because python-pillow must be built with openjpeg support and
jpeg support? Or is it just because in your situation, you were using
jpg pictures?

What about the libxml2 dependency?

No reply since September 2020, I have marked this patch as "Changes Requested".
