fincher is steganography tool for text. It provides a number of strategies for hiding a message within a source text by storing each character as a typo.

The method by which it works is contingent upon the combination of replacement and displacement strategy. See Usage for more information.

The inspiration for fincher comes from "Panopticon", Season 4 Episode 1 in Person of Interest, in which The Machine encodes a message as typos in the dissertation of one of the main characters, Harold Finch.

fincher is currently 0.3.0 and considered an experiment and a project for funsies. I am interested in any contributions & ideas!
