If you're unfamiliar with the Enigma machine, we recommend you click here for a dedicated article. For practical purposes, suffice it to say that it began to be used during World War II. Its main function is to encrypt plain text into cipher text through letter substitution.

With the five websites to simulate an Enigma machine you can encrypt text and also understand the complex encryption principle of the device.

Enigmaco.de

Enigmaco.de is an Enigma simulator that allows you to simulate the encryption of text from an Enigma machine (encrypt plain text).

Main features:

  • The platform has three rotors with five different settings.
  • Share cipher text via email.
  • Show settings, rotor positions, and the Steckers (combinations you choose on the connection panel).

A very good simulator

SummerSideMakerSpace.ca

Universal Enigma Machine Simulator is one of the many Enigma simulator projects available at SummerSideMakerSpace. The system can simulate up to 15 different Enigma machines. Thanks to its simple diagram, you can understand the character assignment within the machine.

Available Enigma machines:

  • Enigma D
  • Enigma I (Army)
  • Norway Enigma (Norenigma)
  • Enigma M3 (Army / Navy)
  • Enigma M4 (Navy)
  • Zählwerk (A-865)
  • Enigma G (G-31)
  • Enigma G (G-111)
  • Railway Enigma (Rocket I)
  • Enigma G (G-260)
  • Enigma G (G-312)
  • Swiss-K
  • Enigma K
  • Enigma KD
  • Tirpitz (Enigma T)

Lysator.Liu.se

Lysator.Liu.se instead of showing you a diagrammatic simulation, shows you a graphic simulation, much easier to understand. The rotors are inside the machine covered by a top lid. When you open the lid you will have access to the rotors and the reflector. To encrypt text, you will need to type plain text using the QWERTZU keyboard.

Features:

  • It has two Enigma machines: Enigma 3 and Enigma 4.
  • Option to change and configure the rotors and the reflector.
  • It has six different rotors and two reflectors.

Very easy to use

Enigma.Louisedada.co.uk

Enigma.Louisedada.co.uk is a website that has all the necessary information to understand how an Enigma machine works. It explains the mechanics and the Daily Key Generation mechanism. It can simulate two machines:

  • Enigma M3 (Navy/Army/AirForce)
  • Enigma M4 (Navy Only)

People.Physik.Hu-Berlin.de

People.Physik.Hu-Berlin.de is an Enigma machine simulator that comes with secure HTTPS connection. The platform has twelve different Enigma machine simulators:

  • I (Army; GAF)
  • M3 (Army; Navy)
  • M4 "Shark" (U-Boats)
  • D (Commercial)
  • K (Swiss)
  • N "Norenigma" (Norway)
  • R "Rocket" (Railway)
  • T "Tirpitz" (Japan)
  • A-865 "Zählwerk" (1928)
  • G-111 (Hungry / Munich)
  • G-260 (Abwehr, Argentina)
  • G-312 (Abwehr / Bletchley)
