Make a Caesar Wheel

The Caesar shift cipher was an early method of encrypting information and is often used as an entrypoint to the world of cryptography, cryptanalysis and cryptology, which is itself an inherently mathematical discipline.

The above challenge was followed a few days later by a further, related challenge:

#TheBletchleyParkChallenge 09 ⚙️ - Make your Caesar Wheel messages harder to break!

If you have a Caesar wheel and know how to use it (see day two’s challenge!) you can make messages harder to break by using a key word (rather than just one shift).https://t.co/Fbl5c0Hb9j
