To reiterate Alex, "yes you can".
Squid supports "proxy over TLS" as well as the old/default "proxy over TCP"
- you use the https_port option
...but getting browsers to support it is challenging. The best way would be
to create a WPAD file that tells browsers to use "HTTPS" instead of
"PROXY". Then you can just use Proxy-Authentication using Basic and you'd
be all set. BTW, Basic has MAJOR performance benefits over any other form
of authentication IMHO. Basic over TLS is the way to go...
eg something like this
---------------- wpad.dat ----------
function FindProxyForURL(url, host)
{
// see how I used 443? If you're going to run a TLS-encrypted proxy, make
it totally appear as a HTTPS server and run it on port 443...
//
if (isPlainHostName(host) || dnsDomainIs(host,"localhost.localdomain") ) {
return "DIRECT";
} else if (isInNet(host, "127.0.0.0", "255.0.0.0") || isInNet(host,
"10.0.0.0", "255.0.0.0") || isInNet(host, "172.16.0.0", "255.240.0.0") ||
isInNet(host, "192.168.0.0", "255.255.0.0") ) {
return "DIRECT";
} else {
//
return "HTTPS secure-squid.com:443";
}
}
