Squid can listen on an https_port for connections. The TLS settings to
challenge for client cert are the same for explicit proxy as you would
find for reverse-proxy.
What you will also find however is that browsers do not do TLS to
proxies, or if they do not without jumping through some other hoops
which are browser dependent.
* Chrome requires that it is started with certain command line options,
AND that a PAC file is used with https:// URI for the proxy detail.
* Firefox requires that PAC file are used with https:// URI for the
proxy detail AND limits the protocol spoken to those proxy to HTTP/2.
* Safari and IE - seem not to support TLS proxy at all yet AFAIK.
