SSL 100

Using defaults in SSL module can lead to insecure protocol usage.

Python 3.6 applies PROTOCOL_TLS as the default value, so if no value is specified and your Python version is detected to be 3.6+ this issue won't be shown.

Fixes

• Use ssl.create_default_context() instead of trying to do this yourself
• Do not use version specifiers, use PROTOCOL_TLS with options disallowing the bad protocols
