Hello,
I noticed that Cloudflare is continuing to follow ECH: Handshake Encryption: Endgame (an ECH update)
According to a report, ECH with the extension value 0xffce
has been targeted, so users cannot use 1.1.1.1
+ ECH in the Chinese mainland.
But I noticed that in the latest version of the draft (draft-ietf-tls-esni-13), the extension values have become 0xfe0d
and 0xfd00
. Does Cloudflare plan to switch to the latest version of the draft?
Best Regards,
Gentry
