TypeError raised in Python 3

[Pablosan]

The cryptography package expects an instance of bytes to be sent to its Fernet.encrypt method: https://github.com/pyca/cryptography/blob/master/cryptography/fernet.py#L63

Since json.dumps is being used to serialize the data before encryption, a string is being passed to the cryptography package. In Python 2 strings are also bytes. In Python 3 they are not, so an explicit translation is required.

It appears that doing something like message.encode('utf-8') (if the Python version is 3.x) would make the cryptography package happy.
