Enigma Machine

A typescript enigma machine

Installation

Using npm:

$ npm i @whambulance/enigma-machine

Import into your project:

import enigma from 'enigma-machine'

Use

enigma-machine currently supports Enigma I rotors 1 through 8, with reflectors UKW b, c, b thin, and c thin.

Initialize the machine as such:

let machine = new enigma
let solvable = 'There is no escape, we pay for the violence of our ancestors.'

let result = machine.solve(solvable)
return result

$ 'cficm ww wi fjuegd, cs ojj zet zxo xsbspyff la cfb wdbqmjfme.'

Set Inserted rotors

Update the rotors currently inserted. Array positions are handled left to right - {0: Left, 1: Middle, 2: Right}

machine.rotorsSelected = [5, 1, 2]

Set Rotor positions

Update the starting positions of the currently inserted rotors. Array positions are handled the same as rotor selection

machine.rotorPositions = [5, 1, 2]

Set Inserted Reflector

Update the currently inserted reflector plate

machine.reflectorSelected = 3

Set Plugboard combinations

Update the inserted plugs for plugboard combinations. Specify an array of two character length strings, each provided string represents a single combination. I.e. ['ab', 'cd'] would make A become B, and D become C.

machine.plugboard = ['bq', 'cr', 'di', 'ej', 'kw', 'mt', 'os', 'px', 'uz', 'gh']
