Simplybius

Made for 2019 April's Fools in Discord API for communicating while in Emoji-only mode.

Requires Python 2 or 3.

Background

The tool is based off an ancient Greek cryptographic device known as Polybius Square.

The idea is that each letter is represented by a pair of coordinates on a 5x5 grid (see article). It's a simple substitution cipher, where each letter is replaced with a two-digit number.

Usage

You can encode or decode messages, from plain or Discord format. Clone the repo, navigate to the target directory, and do the following:

Encode: python . encode message goes here

Encodes a message and outputs polybius square coordinates.

$ python . encode test
44 15 43 44

Decode: python . decode coordinates go here

Decodes coordinates and outputs original message.

$ python . decode 44 15 43 44
TEST

Encode for Discord: python . dencode message goes here

Encodes a message and outputs discord emoji to paste.

$ python . dencode test
:four: :four: :one: :five: :four: :three: :four: :four:

Decode from Discord: python . ddecode emoji codes go here

Decodes pasted emoji and outputs original message.

$ python . ddecode :four: :four: :one: :five: :four: :three: :four: :four:
