This shows how to store words, letters and strings using codes via cloud variables, I only added the letters part, add the numbers at will. The encryption/decryption is easy to expand and enlarge with a good knowledge of scratch. Enjoy! :D This can be used for scoreboards etc. DO NOT use this for chatrooms and/or social media, it is against the rules to do so, sorry for the inconvenience.
Note to admins/mods: This project is used to show users how to encrypt/decrypt text and data, the use of cloud data is inevitable. Why don't enough people read these?!
