Yes, I believe it is possible: * Squid can check (via an https_port configuration option) that a TLS client possesses a certificate signed by a specific CA. * Squid can check (via a ca_cert ACL) that a TLS server uses a certificate signed by a specific CA. This ACL can be applied during SslBump step3 processing, but there may be a way to sneak it in without using SslBump (or such a way can be added by modifying Squid). If ca_cert options are not enough, Squid can check other server certificate properties via a custom certificate validation daemon (which you would have to write). Or one could add support for more properties to the ca_cert ACL.
