If you're getting "Untrusted device" on your Chromecast today, you're not alone. It looks like an expired cert.

It's possible to encrypt traffic without a cert that expires.

I don't know much about how Chromecast works but my bet is that it's like a hacked together lighthttp or nginx server, which is why it needs a SSL cert renewal.

If I remember correctly I have seen an nginx page in combination with some chromecast device.
