I created this ring as a simple yet engaging tool to encode or decode text using a shift cipher, often referred to as a Caesar cipher. You can find more about this fascinating cryptographic method in a Wikipedia article.
This design includes an additional ring featuring letter numbers for enhanced learning and usability. The middle ring rotates freely, which allows you to adjust the number of shifted positions with ease. It’s a delightful toy for kids and a perfect way to introduce them to the basics of cryptology.
