I want to make a save for my game. (It's not just a kind of save that saves coins and stuff it's saves the selected character and etc.) But it's too easy to cheese and rewrite and do everything you want with it.
I want it to be less easy for the user to change things in the save file.
My first idea was to decode and encode it to base64 but it was still way too easy to crack.
If somebody would ask the save file is technically a txt file renamed to save.dat which is just for organization reasons.
