Sphinx Cipher Gadget

A fun toy for kids to learn about cryptography!  Dial up the four character key of your choice and encrypt or decrypt messages based on a unique code.  If you want to make life harder for code-breakers, use "Enigma-mode" and rotate the wheels one click after you encrypt or decrypt each character. Buy two of them and communicate secretly with a friend! Like the Sphinx Password Manager, all Sphinx Ciphers are unique based on their identifier.
