Struct ClientHello

pub struct ClientHello { /* private fields */ }

When a client first connects to a server, it is required to send the ClientHello as its first message.

The ClientHello contains random data, cipher suites, legacy content from <= TLS.12 and extensions.

For Rama however we only focus on the parts which a user might want to inspect and/or set.

Implementations

impl ClientHello
