Indeed, I came across this project while googling the idea! I figured out SSL would be a nice feature to have - surely you wouldn’t want your Star Wars ASCII stream to be tampered with, would you? ;)
When I discovered this as a youngling it totally opened my mind to the crazy possibilities of computers and the internet. Love to see it posted here after all these years!
PRs welcome :) I guess for the curl version it's gonna be tough because you can't really interact with the stream that you receive. You should be able to do it with the telnet version, though
