crypto-enigma: An Enigma machine simulator with display.
The crypto-enigma package is an Enigma machine simulator with rich display and machine state details.
Currently support is only provided for the machine models in most widespread general use during the war years: the I, M3, and M4.
For basic functionality, including some introspection of machine state and the mappings performed, simply
> import Crypto.Enigma
For richer display functionality additionally
> import Crypto.Enigma.Display
(Note that this package assumes support for combining Unicode, without which some output may appear garbled.)

Readme for crypto-enigma-0.0.2.9
[back to package description]crypto-enigma
An Enigma machine simulator with state and encoding display.
Currently support is only provided for those machine models in most widespread general use during the war years: the I, M3, and M4.
This is adapted, as an exercise in learning Haskell, from an earlier learning project written in Mathematica. It is my first Haskell program. A Python version with substantially the same API, plus a command line interface, is also available.
Functionality
Perform message encoding:
>>> enigmaEncoding (configEnigma "b-γ-V-VIII-II" "LFAP" "UX.MO.KZ.AY.EF.PL" "03.17.04.11") "KRIEG"
"GOWNW"
>>> let cfg = configEnigma "c-β-V-VI-VIII" "CDTJ" "AE.BF.CM.DQ.HU.JN.LX.PR.SZ.VW" "05.16.05.12"
>>> putStr $ showEnigmaEncoding cfg "FOLGENDES IST SOFORT BEKANNTZUGEBEN"

Show configuration details:
>>> let cfg = configEnigma "b-γ-V-VIII-II" "LFAP" "UX.MO.KZ.AY.EF.PL" "03.17.04.11"
>>> putStr $ showEnigmaConfigInternal cfg 'K'

Limitations
Note that the correct display of some characters used to represent components (thin Naval rotors) assumes support for Unicode, while some aspects of the display of machine state depend on support for combining Unicode. This is a known limitation that will be addressed in a future release.
Documentation
Full documentation — for the latest release version — is available on Hackage.
Alternatives
For other Haskell Enigma machines see:
This package served as the basis for a Python version, with essentially the same API.
Development status
I'm currently learning and experimenting with some Haskell language features and can't promise the development version will work. More detail about planned releases and activities can be found the list of scheduled milestones and in the list of open issues.
