[$] OpenWrt and self-signed certificates

The move to secure most or all of web traffic using HTTPS is generally agood thing; lots of personal information is exchanged via web browsers,after all. Using HTTPS requires web sites to have TLS certificates,however, which has sometimes been an impediment, though Let's Encrypt has generally solved thatproblem for many. But there are systems out there that may need the HTTPSprotection before their owners even have a chance to procure a certificate,IoT devices and home routers, for example. An October discussion among OpenWrt developers explored this problem a bit.
