You can now Enable Encrypted Client Hello (Encrypted SNI or ESNI/ECH) in Microsoft Edge
How to enable Encrypted Client Hello (ECH) in Microsoft Edge version 105 and above.
Right-click on desktop shortcut of Edge browser, select properties and add this at the end of the target:
--enable-features=EncryptedClientHelloso that it will look like this: (there is a space before --)
preferably turn on these related flags as well to improve the overall experience of this feature.
edge://flags/#dns-https-svcb
edge://flags/#use-dns-https-svcb-alpn
Make sure to go to Edge settings edge://settings/privacy and turn on Secure DNS and choose Clouldflare. now restart the browser, visit this webpage and confirm ECH is enabled.

- 按照步骤设置后
测试通不过？ - Can we use this on Mac? If so, how?
- No, you can not, it only works to disable ECH, not to enable it.
You have to run Edge with a parameter. This policy is useless.

https://postimg.cc/B8tjxQb3 - https://postimg.cc/jW9Lv0n7I only talked about the command line switch though, and it does work, Group policy used to manage it doesn't enforce it like this command line switch does.
Hello,
I tried what you said with Edge 110.0.1587.56. Cloudflare shows working at https://www.cloudflare.com/ssl/encrypted-sni/ but not https://defo.ie/ech-check.php
I did the following:
1) Enable "Use DNS https alpn" at edge://flags/#use-dns-https-svcb-alpn
(I don't see edge://flags/#dns-https-svcb )
2) Edit Edge shortcut to include --enable-features=EncryptedClientHello
3) Kill all Edge processes with "taskkill /im msedge.exe /f"
4) Open Edge and go to both sites to see if ESNI works
It shows that ESNI is working on Cloudflare site but not defo.ie. Any thoughts if the defo.ie site may be not working or something my side/ISP? My main DNS servers on my Asus router are 1.1.1.1 and 9.9.9.9 with IPv6 equivalent and utilize DoT.I seem to get mixed results with Secure DNS and Secure SNI when I refresh and do Check My Browser or kill msedge and try again. Secure SNI will show not working at first and Secure DNS working. When I refresh, Secure DNS will show not working but Secure SNI working. Both DNS providers support DNSSEC. Two things here Secure DNS and Secure SNI but hoping to use two DNS providers and if 9.9.9.9 doesn't support Secure SNI, is there an alternative I can try?
Thanks,
JasonI just tried this again in Edge Version 114.0.1823.58 (Official build) (64-bit) and it's working
Use the same procedure I explained in my post, it should work, just make sure Startup boost isn't on so that when you change the command line flags it will take effect immediately.
Cloudflare's website is also updated to support ECH and it detects it too.
Here i checked it with Wireshark too for this site: https://defo.ie/ech-check.php
Not working in new Edge 115 version and startup boost is disabled.
- does this still work? there are no such flags
edge://flags/#dns-https-svcb
edge://flags/#use-dns-https-svcb-alpn- it doesn't seem to work with hiddify, but why would I need it then)
