Scout Message Encoder

This is a rotary message cipher designed specifically for scouting activities. Its structure is intended to facilitate the encoding and decoding of secret messages manually and playfully, incorporating the Spanish alphabet (including the letter Ñ).

🧩 Cipher Components

1. Outer Dial (Fixed)
   It is the largest disc and contains the complete alphabet clockwise, from A to Z, including Ñ. This disc remains fixed during encryption.
2. Central Dial (Rotating)
   Intermediate disc that also contains the complete Spanish alphabet. On this dial is a fleur-de-lis, which represents the letter A and serves as a reference point for code alignment.
3. Internal Thread
   Central piece that holds the discs together and allows the central dial to rotate freely over the outer disc without coming loose.

🧭 How to Use

The cipher works as a simple substitution disc. Here are the steps to use it:

1. Align the fleur-de-lis with the key letter
   Decide what type of encoding you want to apply. For example, if you want to use the code A = D, you must rotate the central dial until the fleur-de-lis (representing A) is aligned with the letter D of the outer dial.
2. Encode the message
   For each letter of the original message, find its equivalent on the central dial and write down the corresponding letter that appears on the outer dial directly opposite.
3. Decode
   To decipher, simply reverse the process: align the fleur-de-lis with the key letter again, but now look for each encoded letter on the outer dial and translate it with its equivalent from the central dial.

📌 Example

• Original message: "SCOUT"
• Key: A = D (fleur-de-lis aligned with the D of the outer disc)
• Procedure:
  • S (central dial) → V (outer dial)
  • C → F
  • O → R
  • U → X
  • T → W
• Encrypted result: VFRXW
