ECH 變成 Standards Track 了
#client #clienthello #ech #encrypted #encryption #esni #header #hello #https #rfc #ssl #standards #tls #track
Just found out that you can get #ESNI ^W #ECH #DNS queries working in #Firefox without having to run my own DNS over HTTPS server.
Just set network.dns.native_https_query to true. Bonus points for network.dns.preferIPv6 to make it stop preferring #IPv4 for some reason.
You obviously have to find a way of getting DNS traffic in and out of your network safely. I spread it out over a couple of servers that I host.
We had lots of queries on why TLS ECH is not good/good, so shedding some light on why it was conceived.
(formerly called Encrypted SNI #ESNI)
Attached: 1 image We've added more info on a use case for #TLS Encrypted ClientHello #ECH in our blog post on how to disable it for Google Chrome. The paper that studies "to prevent censors from learning the server names" is now cited 👇 https://chasersystems.com/blog/disabling-encrypted-clienthello-in-google-chrome-and-why/ Image from: china-briefing[.]com
Google Chrome v117 turned on TLS Encrypted ClientHello by default (on 27 Sep?) This will impact the effectiveness and accuracy of outbound traffic filtering* - for those who've implemented it (regardless of vendor.) We've written a short blog post on disabling it with PowerShell, Windows Registry and Google Chrome UI for those who may need to roll this out ASAP and regain visibility. (Disclosure: we are a vendor of an outbound filtering solution and this has impacted our customers already.)
*for many websites, the domain name visibility during an HTTPS handshake will no longer be available to firewalls/proxies (unless they were terminating.)

I tidigare poddavsnitt har vi förklarat hur vikten av att använda VPN-tjänster på publika wifi-nät har minskat. I veckans podd förklarar vi varför ”krypterade hälsningar” minskar behovet ytterligare (på sikt).
