I've always thought steganography was really cool & clever (even if not usually super practical).

And meanwhile, the LXMF paper/sneakernet-type system seemed like a *perfect* fit for it.

In an effort to see "how would this even look in Sideband", I engaged in some hackery, and wanted to share it here.

1) Clean message history to start


2) Send a paper message the normal way, new dropdown option, "Save in Image"


3) Two modes: one with higher capacity but won't survive compression, and a more robust but lower capacity one.


4) Pops open the share dialog.


5) For my test I just sent to google photos for an easy and fast way to get the image down on my laptop, and here you can see the image


6) You can see the downloaded file on my laptop, and my laptop's Sideband with no message history yet


7) Same flow as other paper messages on the ingest, but now a 'From Image' button option


8) Pick file


9) Confirmation!



My Python is very rough and most of my past work with it was ML-type stuff, so this is also an invitation to refine on this technique! Note that i'm leaving out the Sideband-specific stuff since that just uses the existing paper message scaffolding, should be trivial for anyone to add that in). It's currently just a ~300 line single python file, and can be seen here: https://gist.github.com/KenAKAFrosty/d2b98ec07ac2b13f6a804d1571780d71
