Storing API keys securely

Dear Dataiku Team,

Thank you for all your good work with Dataiku environment - we are looking forward to using new functionality with Dataiku 7!

We are now experimenting with builidng API connections in between nodes - I was able to establish the connection using the code from here:

import dataikuapi
host = "http://localhost:11200"
apiKey = "<MY_SECRET_KEY>"
client = dataikuapi.DSSClient(host, apiKey)

# client is now a DSSClient and can perform all authorized actions.
client.list_project_keys()

How would you approach the topic of security here: secret key is not very sercret if it is hard coded. Does Dataiku offers some safe way of storing it in the environment?

Thank you,
Filip
