# 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
