How to upgrade TLS to v 1.2 in Python (django)

I implemented Dwolla for ACH payments in Django. Now I want to upgrade TLS version to 1.2 to secure the process. What will be the procedure?

Hi @Haseeb_Rehman, Dynamic languages such as PHP, Ruby and Python rely on the underlying operating system’s OpenSSL version. The OpenSSL version can be obtained by running the openssl version command. I would also recommend using the latest supported version of Python as well.

Django server is deployed on heroku. I checked the version of OpenSSL on heroku and it it 1.1.1. Does OpenSSL 1.1.1 support TLS 1.2?
