Enigma Simulator in Rust

This project is a simple implementation of the Enigma machine in Rust. It allows users to input a message, configure the rotor and reflector settings, and encrypt or decrypt the message.

Installation

Ensure you have Rust installed on your system. If not, install it using rustup:

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

After installing Rust, install the crate:

cargo install enigmify

Usage

Run the program:

enigmify

The program will prompt you to enter:

1. The message to encrypt.
2. The wiring configuration for rotor 1.
3. The wiring configuration for rotor 2.
4. The wiring configuration for the reflector.

Example input:

Enter the message to encrypt:
HELLO
Enter rotor 1 wiring:
EKMFLGDQVZNTOWYHXUSPAIBRCJ
Enter rotor 2 wiring:
AJDKSIRUXBLHWTMCQGZNPYFVOE
Enter reflector wiring:
YRUHQSLDPXNGOKMIEBFZCWVJAT

Example output:

Encrypted: ZEBBW
Decrypted: HELLO

How It Works

• The rotors shift characters based on predefined wiring and rotate with each encryption step.
• The reflector substitutes letters in a symmetric manner.
• The encryption process is reversible, meaning decrypting an encrypted message with the same settings will return the original message.
