When saving a file, you should probably write a backup file first, then overwrite the save file, just incase the computer crashes.
And an easy way of encrypting your data, is just to invert every bit, or byte. Then save. Upon reading, invert again to read the correct data. It's never going to be uncrackable and anyone wanting to enjoy a game would really crack the save file.
