!!! Overview
[{$pagename}] describes a Step within the [TLS Handshake] process.

The Client sends the client [Certificate], __if the server requested one__. 

There are subtle variations between versions (with [SSLv3], the client must __omit__ this message if it does not have a certificate; with [TLS 1.0]+, in the same situation, it must send a Certificate message with an __empty list__ of certificates).
