Detailed Description

Simplified implementation of the Enigma machine polyalphabetic cipher.

Simulates the Enigma's rotor mechanism where each keypress advances the rotors, creating a different substitution alphabet for each character. Uses multiple rotors with stepping mechanism and a reflector.

◆ constructor()

EnigmaCipher::constructor	(		rotors:string[] = [ "EKMFLGDQVZNTOWYHXUSPAIBRCJ", "AJDKSIRUXBLHWTMCQGZNPYFVOE", "BDFHJLCPRTXVZNYEIWGAKMUSQO" ],
			reflector:string = "YRUHQSLDPXNGOKMIEBFZCWVJAT" )

inline

Constructor for Enigma cipher.

Parameters

rotors	Array of rotor substitution alphabets (default: 3 historical rotors)
reflector	Reflector substitution alphabet (default: historical reflector B)

Initializes the Enigma machine with specified rotors and reflector. All rotors start at position 0.

Definition at line 53 of file enigma.ts.

Field Documentation

◆ pad0

rotors EnigmaCipher::__pad0__

Array of rotor substitution alphabets.

Each rotor defines a substitution alphabet that rotates with each use

Definition at line 32 of file enigma.ts.

◆ pad1

reflector EnigmaCipher::__pad1__

Reflector alphabet for the return path.

The reflector ensures that encryption and decryption are symmetric

Definition at line 38 of file enigma.ts.

◆ pad2

positions EnigmaCipher::__pad2__

Current positions of each rotor (0-25)

Tracks the rotation state of each rotor for proper stepping

Definition at line 44 of file enigma.ts.

◆ CipherName

readonly EnigmaCipher::CipherName = "Enigma"

Identifier name for this cipher.

Definition at line 26 of file enigma.ts.
