I’m adding basic key based XOR obfuscation now. Only works with ASCII right now but I’ll be adding UTF-8 support soon.
For encryption, going to go with AES.
Turning on obfuscation and encryption will both be options. Neither will protect against people determined to get into or modify the files but it will prevent most normal people from casually modifying even more so. You don’t want to store sensitive info in the files either it will just be an option for devs who don’t want their saved games to be modified so easily.
