Encryption is fundamental to security. So this task is about demonstrating and using the python encryption library. Base your investigation on http://docs.python-guide.org/en/latest/scenarios/crypto/ (don't forget to use pip3.6). Once you can demonstrate it working, input a string (using a GUI), encrypt it, store it in a file, retrieve it and finally decrypt and display it underneath your input. I will be impressed if you also use Pickle and Unpickle - tell me what issues you encountered. 

Silver Level:

Now enhance your bronze level by establishing a link with a server database (MYSQL, MS SQL Server, PostreSQL, and so on). Save your encrypted data into the database and retrieve from the database. You must validate (and demonstrate) that the link is in fact secure.You can also use database facilities for encrypted columns and so on.

Note this is a non-trivial assignment (seehttps://stackoverflow.com/questions/21122847/encryption-using-python-and-postgresql). So I am looking for a credible attempt and an explanation of what you tried and so on. 

Gold Level.

After complaints from certain students in previous semesters and advice from Dr. Jeff followed by counselling from Dr. Peter, I have simplified this level. All you have to do is to work through the tutorial at https://cryptography.io/en/latest/x509/tutorial/. You will need to demonstrate how you did the tutorial, show me personalised snippets that run and so on. It is all about "your server" so you will be doing something with LINUX in a VM.
