Looking at https://letsencrypt.org/docs/certificates-for-localhost/ they mention that "modern" browsers let you make insecure connections to 127.0.0.1. Tested locally with a secure website connecting to ws://127.0.0.1 and it works fine. Which browsers do or don't support it I'm not sure though, but it could be enough for your use-case?

It would be a shame because it's such a convenient solution. 4) It's also a shame how the Internet has become - I still have a mindset of the year 2000 where the web was not really a significant resource of criminal intent. I understand this can lead to misunderstanding ;-) 5) Thanks for all the comments - I actually learnt a lot regarding security !
