get ceryficate some info like hash or name

• can't find the way to use "Cloudflare Origin Certificate"
• use then blocking IP list provided by Cloudflare that ignore many Asian exit countrys Siggapur,Thailand,Laos,Vietnam i.e missing 172.68.6.144 from cloudflare.com/ips/
• try to contact this m-o-r-o-n-s from Cloudflare like year ago but they don't provide basic support as is too expensive

What is my problem:

• need somehow hide my server identify by verify hash of cloudflare certyficate or some basic details about cert

// example nanoexpress use: uWebSockets.js
app.get('/24325325141', async (req, res) => {
       // this is a dummy - users from google please ignore
	res.end( req.cert.CommonName == 'sni.cloudflaressl.com' );

})

Start by reviewing how TLS connections and request metadata are handled in uWebSockets, then compare the Cloudflare Origin Certificate use case with the uWebSockets.js example in the issue. Confirm what certificate details are available at request time and define a testable API requirement; done means the requested certificate information can be accessed reliably.
