buildEnigmaMachine

public static EnigmaMachine buildEnigmaMachine(int r1,
                                               int r2,
                                               int r3,
                                               int refl,
                                               char startPos1,
                                               char startPos2,
                                               char startPos3,
                                               boolean stepping)

This creates an enigma machine, given its characteristics.

Parameters:

r1 - is the type of rotor 1 (right rotor)

r2 - is the type of rotor 2 (middle rotor)

r3 - is the type of rotor 3 (left rotor)

refl - is the type of the reflector

startPos1 - is the start position of rotor 1

startPos2 - is the start position of rotor 1

startPos3 - is the start position of rotor 1

stepping - specifies if rotors step (true is the default position and the only one that can matych the behaviour of the mentioned emulator; setting stepping to false allows you to test the rotors independently of your machine doing the stepping correctly.

Returns:

an EnigmaMachine with the given characteristics

testEnigmaMachine

public static boolean testEnigmaMachine(EnigmaMachine M3,
                                        java.lang.String plainText)

Tests an EnigmaMachine with a given plaintext. It first encodes the plaintext into a cyphertext. Then it runs the cyphertext into the enigma machine obtaining a decyphered text which is verified if it matches with the original plaintext; the result of this verification is returned. If in verbose mode, it prints the enigma machine before and after encoding as well as the plaintext, cyphertext, decyphertext.

Parameters:

M3 - is an enigma machine

plainText - is a plaintext

Returns:

true if and only if M3 encodes and decodes compatibly (i.e. M3 applied to result of M3 applied to plaintext equals plaintext)

main

public static void main(java.lang.String[] args)

Provides a basic set of testing for the EnigmaMachine class.

Parameters:
