Encrypt your messages with a keyword/phrase. Might not work with non-English characters. Also decrypts, but requires a keyword. Unfortunately, due to Scratch recognizing "a" as "A", this does not keep case. This also might not work with tabs and enters. It does work with regular spaces, though. "S" to show output. "H" to hide output.
Uses something similar to a vigenere encryption. 10/7/2019 - Created project 10/8/2019 - Created scripts and sprites and everything 10/8/2019 - Shared Project 10/9/2019 - Slight aesthetic improvements
