Encrypted server name indication (ESNI) is an essential feature for keeping user browsing data private. It ensures that snooping third parties cannot spy on the TLS handshake process to determine which websites users are visiting. Se hela listan på blog.cloudflare.com SNI, or Server Name Indication, is an addition to the TLS encryption protocol that enables a client device to specify the domain name it is trying to reach in the first step of the TLS handshake, preventing common name mismatch errors. The purpose of SNI encryption is to prevent that and aid privacy. Replacing cleartext SNI transmission by an encrypted variant will improve the privacy and reliability of TLS connections, but the design of proper SNI encryption solutions is difficult.

Sni encryption

Replacing cleartext SNI transmission by an encrypted variant will improve the privacy and reliability of TLS connections, but the design of proper SNI encryption solutions is difficult. In the past, there have been multiple attempts at defining SNI encryption. These The simplest SNI encryption designs replace in the initial TLS exchange the clear text SNI with an encrypted value, using a key known to the multiplexed server. Regardless of the encryption used, these designs can be broken by a simple replay attack, which works as follow: If the SNI is unencrypted and required to be always present, this scheme will work all the time.
