Certificate sha256

KOM

You have to check every certificate in the chain. See my image. Click on each certificate in the chain and check their details for SHA-1. In my example, the middle certificate was SHA-1 until I replaced that cert with an updated bundle cert.

Very strange!

When you open the site looks like is attach *sitecert.png
When I go in certification path attach * site-path

You need to check the topmost (root) one as well. Then go and get the updated cert bundle from them.

Everything is updated. The certificate is already signed as sha256 only when going pro squid it comes out as sha128. :'(

You could try the squid option "sslproxy_cert_sign_hash",

I dont know actually if squid 3.4.10 support sha256 or higher.

Maybe its possible with the squid version 3.5.3 or higher.

It is fixed from Version: 3.5.0.1 (Squid)

You can update the squid pfsense?

I found the new version of squid in pfsense repository.

https://files.pfsense.org/packages/10/All/squid-3.5.3-amd64.pbi

How do I get the packages install this?

musicwizard

beta 0.2.8
platform: 2.2

https://github.com/pfsense/pfsense-packages/blob/master/pkg_config.10.xml#L1046

System - Packages.

Regarding this "issue" - fascinating. You people break all encryption by the SSL bump brainfart, and then are concerned about SHA1. facepalm

Stop hijacking SSL and you won't have any such issue! ::) ::) ::)

S. Kirschner

Yes its the version 3.4.10 available in the public Package Repository.

If you would like to install the squid-3.5.3-… from the pfsense files then you have to "build" your own Custom Package Repository and manipulate the "pkg_config.10.xml".

But be carefull, dont try it in a live environment. Also please read about "peak and splice" on the squid homepage.

Here is the link to Creating a Custom Package Repository https://doc.pfsense.org/index.php/Creating_a_Custom_Package_Repository

edit:

BTW you could see the version of installed squid version by enabling ssh , and connect via ssh to your pfsense server and type squid -v. Then you see the build options and version number.
