Solution

There are some Python packages worth checking out that deal with cryptography.

Cryptography

PyCrypto

A simple example from cryptography would be the following:

from cryptography.fernet import Fernet
key = Fernet.generate_key()
cipher_suite = Fernet(key)
cipher_text = cipher_suite.encrypt(b"A really secret message. Not for prying eyes.")
plain_text = cipher_suite.decrypt(cipher_text)
