Encrypt credentials

[IanStorm]

Hey,
I just included this node in my personal Node-RED flow; it works like a charm. 👍
One thing I saw however: The credentials are stored as plain text in the flows.json file. I think they should be stored inside flows_cred.json, with the advantage of auto-encryption/-decryption done by Node-RED.
So far I don't have experience in creating nodes for Node-RED... I was thinking to give it a try and create a PR to fix that issue. Is this repo still active?
Thanks in advance.

PR is welcome. I am not javascript developer, and currently I do not have enough time to work on this project.

And you can also fork this repo and submit npm, to make you forked node searchable from node-red instance.

Thanks for your reply.
I also thought about forking the repo, but definitely prefer to first try to fix it here. (Plus, I didn't want to create another fork of a fork.)
I value your precious time, and I am trying to provide a PR soon.

Beside not have enough time, another reason I not interest in this feature personally is that I use environment variable to refer the password, which injected by kubernetes.

Actually, credential should store in flow_cred.json, and I am looking forward for your PR.
