This is supported in Squid-3.0 for accelerator type setups using the
https_port directive and the certificate related acls.

Actually it is even supported for proxy operation using https_port, but to
our knowledge there is no browsers supporting the use of SSL connections
to the proxy. The use of SSL is a requirement for certificate based
authentication as certificates is a property of SSL, so until there is
browsers implementing SSL to proxies such authentication is not possible
for proxied Internet requests.
