Procrat / stegano

Stegano decoding

Stegano automation

A forever-WIP library intent to find hidden messages. Currently supports

• PNG & (animated) GIF images, and
• Binary, base32, base58, base64, base85 and morse encoded text.

More specifically for images, we look at

• any place in the format where data can be hidden that an image viewer wouldn't show, and
• the image and its histogram per channel (R, G, B, and A).

Usage

./detect.py 'c2VjcmV0IG1lc3NhZ2UK'

or

./detect.py some-file.png
