Proxy DNS over HTTPS requests
bash
doh-proxy-rs --server --listen=0.0.0.0:443 --upstream=1.1.1.1:53 --identity=./server.pfx --password=foobar
The server requires a PKCS#12 identity. You can generate it from a key pair in PEM format:
bash
openssl pkcs12 -export -out server.pfx -inkey key.pem -in cert.pem [-certfile chain.pem]
PEM certificate support depends on native-tls
(sfackler/rust-native-tls#27).
