Encrypted Client Hello - the last puzzle piece to privacy
Cloudflare introduces Encrypted Client Hello (ECH), a new privacy standard that masks the Server Name Indication (SNI) used in TLS handshakes, preventing networks from determining which websites users are visiting. ECH is available on all Cloudflare plans and can be enabled by website owners who want to ensure user privacy. Browsers like Google Chrome and Firefox are already ramping up support for this technology. By using ECH, intermediaries will only see identical TLS handshakes indicating a connection to cloudflare-ech.com rather than the actual websites being visited. Cloudflare aims to encourage widespread adoption of ECH to enhance privacy on the internet and eventually solve it completely.
