Rotor Initial Positions (0-25 for A-Z)

Rotor 1 (Rightmost)

Rotor 2

Rotor 3

Rotor 4

Rotor 5 (Leftmost)

How to Use & Machine Configuration

This simulator uses an Enigma-like mechanism with 5 randomly generated rotors and a reflector. For successful decryption, the **Rotor Initial Positions** and **Plugboard Settings** must be identical to those used during encryption.

The core machine wirings (rotors and reflector) are randomly generated once when the page loads, ensuring a unique machine setup.
