you should encrypt first, then save as json
This code not tested, but should work or only need minor modification.
at top:

import json

after line 14:

        self.save_settings(filename)

def save_settings(self, filename):
    with filename.open('w') as f:
        json.dump(self.settings, f)

# for reading back in:
def load_file(self, filename):
    with filename.open('r') as f:
        self.settings = json.load(f)
