IMHO you should remove default key and throw error, when key is not provided during installation

DEFAULT_KEY = 'Falldog'

Thanks for your suggestion. I will remove default key setting
for both support install by pip and setup.py, need more testing

1. pip install, I need to try read the password from os.env rather than STDIN
2. setup.py should get the ability to read password from STDIN
