Is TLS SNI encrypted?

SNI solves this problem by indicating which website the client is trying to reach. Paradoxically, no encryption can take place until after the TLS handshake is successfully completed using SNI. As a result, regular SNI is not encrypted because the client hello message is sent at the start of the TLS handshake.

How does TLS SNI work?

How does SNI work in the TLS handshake?

SNI adds the domain name to the TLS handshake process, so that the TLS process reaches the right domain name and receives the correct SSL certificate, enabling the rest of the TLS handshake to proceed as normal. Specifically, SNI includes the hostname in the Client Hello message, or the very first step of a TLS handshake. What is a hostname?

When to use Server Name Indication in TLS?
