have you tried this simple technique to bypass censorship? (programming.dev)

hello,

TLDR: just enable DoH

Today, my friend and I were talking about SNI and deep packet analysis shit done by the government. I insisted that since they do this kind of shit they can block access to certain sites like TPB and other freedom websites. he suggested that I just enable DoH in firefox and see the magic happen. I didn't believe him until I enabled DoH and magic. I can access every censored website.

so just saying that sometimes the bypass is much simpler than we think!

also I am thinking that even if the DNS request is encrypted cant they see the TLS client hello message and block it? or is it impossible?

You have weak dpi system in ur country then. the gfw and dpi aint just playing with ip blocks no more—they straight up dropping any ech packets on sight and nuking quic udp 443 to force that tcp fallback so they can sniff your sni while using active probing and ja3 fingerprinting to instant-kill any encrypted stream that dont look like a regular chrome handshake 1:1 and now they even doin alcpn hijacking and timing analysis
