PyEnigmaMachine

This is a simple implementation of the Enigma Machine in python. It should be mostly be a correct emulation of the Enigma Machine though the double step sequence is not implemented. It emulates the standard settings from the German Railway (Rocket) model that was introduced in 1941.

Usage is as following:

#Create Machine A
enigmaMachineA = enigmaMachine()

#Add rotorWheel
enigmaMachineA.addWheel("JGDQOXUSCAMIFRVTPNEWKBLZYH", "Q")
enigmaMachineA.addWheel("NTZPSFBOKMWRCJDIVLAEYUXHGQ", "E")
enigmaMachineA.addWheel("JVIUBHTCDYAKEQZPOSGXNRMWFL", "V")

#Add reflector
enigmaMachineA.addReflector("QYHOGNECVPUZTFDJAXWMKISRBL")


#Create Machine B with same settings
enigmaMachineB = enigmaMachine()

#Add rotorWheel
enigmaMachineB.addWheel("JGDQOXUSCAMIFRVTPNEWKBLZYH", "Q")
enigmaMachineB.addWheel("NTZPSFBOKMWRCJDIVLAEYUXHGQ", "E")
enigmaMachineB.addWheel("JVIUBHTCDYAKEQZPOSGXNRMWFL", "V")

#Add reflector
enigmaMachineB.addReflector("QYHOGNECVPUZTFDJAXWMKISRBL")

#Communication
message = "iloveyou"
print("Message: " + message)

encryptedMessage = enigmaMachineA.encryptStr(message)
print("Encrypted Message: " + encryptedMessage)

decryptedMessage = enigmaMachineB.decryptStr(encryptedMessage)
print("Decrypted Message: " + decryptedMessage)
