sooo this is a custom encryption software and there is now decryption code in it lol (I know the"set the style of encryption" code is super chunky,but I don't know how to make it less so.)(Also,it is not recommended that you use double-digit decryption style because the code decrypts it digit by digit.You can still use double-digit encryption since the inputs are single-digit.)
Thanks to @Scratch-Minion for the original project.
