WSS?

[maj-tom]

Are secure (TLS/SSL) WebSockets supported? If so, does the module handle the security and bridge unencrypted TCP traffic to the proxied server?

Yes

SSL is supported via nginx

It is the same as proxying HTTPS to a HTTP upstream

browser -> nginx(443) is encrypted by ssl

nginx(module) -> proxied_server:5900 is not encrypted

    # HTTPS server
    #   
    server {
        listen       443 ssl;
        server_name ....................;

        ssl_certificate     ..........................
        ssl_certificate_key ...................

        location /websockify {
            websockify_pass proxied_server:5900;
        }
    }
