Program Name : Enigma-Machine-Simulator

Author : M.Fatih Altuntaş

Description : This is a simulator of enigma machine(m3) on python, it runs exactly same real enigma machine

This simulators implemented based on enigma m3 machine, below image shows it

Extra information about machine such as properties , how it works and egg...Please go to this link

How to run

python3 enigma.py -m ENIGMA -sp KET -n2 E -n3 V 

Argumets

• -m plaintext
• -sp,Initial positons of rotors,for above rotor1=K,rotor2=E and rotor3=T
• -n2,notch positon of rotor2
• -n1,notch positon of rotor2
• -r,reflactor,

Output

Fatihs-MacBook-Pro:Enigma fatih$ python3 enigma.py -m ENIGMA -sp KET -n2 E -n3 V 
Running
Message is  ENIGMA
Initial posion of rotor  KET
Notch posion of rotor3 and rotor2  V E
------------------------------------------------------------------------------------------------------------------------
Enigma : ENIGMA  ->  HUBNEQ

For revert plaintext,you can run script again with same config, as follows

Fatihs-MacBook-Pro:Enigma fatih$ python3 enigma.py -m HUBNEQ -sp KET -n2 E -n3 V 
Running
Message is  HUBNEQ
Initial posion of rotor  KET
Notch posion of rotor3 and rotor2  V E
------------------------------------------------------------------------------------------------------------------------
Enigma : HUBNEQ  ->  ENIGMA

Detailed outputs as follows,it show each steps of proccesing
