# spy
Inspired by TURN and Robin David's awesome python library
I found this awesome Python library: https://github.com/RobinDavid/LSB-Steganography
It let's you hide text in images, binaries in images and images in images.
I was interesting in hiding text messages in images. After seeing https://en.wikipedia.org/wiki/Turn:_Washington's_Spies I
thought this was cool.
So using the library, I take an image and text and hide the text in there. The library produces a new image (PNG) that has the message in it.
I have a second script that extracts the text.
The images look the same to my eyes.
A future test would be to run a deep learning library or image analysis tool on the images to see if they spot the bits. They should be able to. A future NiFi tool would be to spot hidden images.
