Re: HTTPS chrome - SHA1 this page is insecure

The answer why you only see it on Chrome is because since Chrome >= 41: 

"Sites with end-entity certificates that expire on or after 1 January 2017, and which include a SHA-1-based signature as part of the certificate chain, will be treated as “affirmatively insecure”. Subresources from such domain will be treated as “active mixed content”."

Sounds like you are running an old Squid version.

See http://www.squid-cache.org/Doc/config/sslproxy_cert_sign_hash/

I have not checked, but I doubt we mimic the signing algorithm (because
it would make client-Squid communication less secure?). If we do, we
should update the wiki page that lists what is being mimicked.


HTH,
