[squid-users] Tutorial for better authentication than basic

Here's a question:  if I use SSL or TLS encryption between squid and browser, would even the basic auth login be encrypted?  
I'm thinking that instead of trying to use the proxy to SSH through, I could use something like shellinabox over the proxy if the link is encrypted.  This would be much easier and serve the purpose.
According to this link, it seems pretty straightforward to get Firefox or Chrome to do it:  wiki.squid-cache.org/Features/HTTPS#Chrome
Would the default config located at wiki.squid-cache.org/SquidFaq/ConfiguringSquid#Squid-3.5_default_config  allow this?

The security level with Digest depends on the nonce lifetime and reuse 
counter, both of which you can tune to your liking. The shorter those 
are the more secure, up to the point where it is a purely one-time 
token. That said, some clients (most often browsers) have big trouble 
managing nonces in correct order and with dozens of connections open to 
the proxy - and then there are Squid bugs. So tuning those is not as 
easy as it should be.

NTLM does not work over the Internet. Kerberos might, but not very well. 
They are connection-oriented authentication schemes designed for use in 
LAN environments. So for your described situation they are not useful 
even if you were willing to open the ports.
