@gitsrc I'm aware, but uTLS probably still leaks some info from its dynamic behavior (cipher negotiation, key exchange).

@frankang http/2 is just http/2 cleartext over tls. They use the same tls stack.

Why not borrow the chrome web stack by designing a chrome app ?

@gitsrc Chrome app support was discontinued several years ago, and it was the only way you can use raw tcp sockets inside Chrome, not Chrome extensions.

Ok, but how come wss+tls+cf actually works and h2 doesn't? (I'm writing this while connected to v2ray via mentioned stack)

and, why haven't you tested trojan 1.14.0? they also added FF 71.0 fingerprint 2d ago (trojan-gfw/trojan@4ab621d)

@itshaadi who said wss+tls+cf doesn't work?

@itshaadi

You said they use the same TLS stack. well, h2 doesn't work. but wss+tls+cf works! (although not with ECC CA-2 certs you can read more about it here). but still, h2 doesn't work at all. yet they use the same TLS stack. so then how come wss+tls+cf works?

What do you "h2" means? like Your client <--HTTP/2--> Your server, and without using Cloudflare as reserve proxy? Then Iran Government block your server address?

Client <--HTTP/2--> Server with, or without Cloudflare doesn't matter. it's always the same result (connection doesn't reach the server). I get RST after Client Hello. @tomac4t

cbeuw's Cloak sames archive similar result in mercury and tlsfingerprint.io.
https://tlsfingerprint.io/id/bbf04e5f1881f506

But it choose listen direct on 443 and I'm worry it's site cert will be a weak point.

Cloak have some useful feature like direct udp forward support, and support multi-forward group.

Cloak 和 Chromium 的指纹一致是因为它用的是 uTLS… @bash99

Thanks, got it.

if we can got the traffic distribution passed on GFW, maybe some new way can be found.
perhaps Zoom and MS teams use many traffic recently.

Hi, @tomac4t, @klzgrad, I'm a newbie, I wonder how you guys get the TLS fingerprint hash in tlsfingerprint.io?
i.e., the 712d38dcc66eb900 in the https://tlsfingerprint.io/id/712d38dcc66eb900
