Store private key for python wsgi application using ligthttpd server

Question

I am implementing ECDH algorighm using python wsgi application using lighttpd server. What is the conventional way to store the private key from my python script?

Answer 1

If you want to store it permanently, you can store it to a file

with open('file', 'rw') as f:
    f.write(private_key_variable)

if you want to keep it as an environment variable you can do it as such

import os

# Set environment variables
os.environ['PRIVATE_KEY'] = private_key_variable
