DNS over TLS

[Amit Sharma]

Hi All,

I am making PWA and problem is with  WebTransport there is no way to establish DoT (DNS over TLS ) connection, anyone know if it's possible here 

[Yutaka Hirano]

Sorry, can you describe your problem a bit more in detail?

You want to establish a WebTransport over HTTP/3 connection and you want to use DoT for the DNS resolution, right?

Yes, I want to establish DoT connection from PWA app (which use WebTransport - https://web.dev/webtransport/ ).

Hi,

We want to implement the DNS over TLS functionality, for that we need to create the TLS socket with DNS server, 

I am able to do it chrome app by using "chrome.sockets.tcp.secure" API, but this API is not available in PWA, 

so we are looking something similar so that we can establish TLS socket, once the socket established we can send DNS data over it.

Thanks

Are you certain about that? When you utilize "web_accessible_resources" you should be able to use any chrome.* API in the page loaded at chrome-extension://.

Ah I think I understand what you are trying to do. You want to implement DNS over TLS using WebTransport over HTTP/3, right?

WebTransport over HTTP/3 is not a raw socket API and you cannot use it to implement DNS over TLS I think.
