Re: SQUID3 HTTPs forward proxy and sha256/512 authentication

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Guys,

I just need an HTTPS proxy that can handle both http and https connections for authorised clients only. I tried to configure something like it's described here http://www.mail-archive.com/squid-users@xxxxxxxxxxxxxxx/msg93592.html
Forward HTTPs proxy with digest_pw_auth for example.

But I am getting the same error clientNegotiateSSL: Error negotiating SSL connection on FD 6: error:1407609C:SSL routines:SSL23_GET_CLIENT_HELLO:http request (1/-1) if I try to open a website (http or https) with proxy enabled on browser settings: protocol https, server proxy-squid.com, port 3129, test:test (user/password)

If I understood correctly from our communication its not possible to configure squid like it described above. Or ther

browser(proxy settings: protocol - https, server -proxy-squid.com, port -3129, test:test (user/password)) <------> Squid Server (https_port 3129 with certificate)<--------HTTP or HTTPS connection-------> Destination

Description of the connection flow:
1. a client set proxy settings of his browser settings: https, server:port, user:password
2. a clients credentials were verified by squid server,  browser asks the proxy to establish a virtual tunnel between itself and remote server 
3. when a client enter https://example.com or http://example.com then browser sends encrypted data through the squid proxy 

Is it possible?

Thanks,
Anton

I think you and Yuri are talking past each other on this.

This page has what you want to know
<http://wiki.squid-cache.org/Features/HTTPS>. Yuri was talking about
section-2 connections, but I read your query as being closer to
section-4 connections.

Squid does Basic, Digest, NTLM, Negotiate, and (with a patch) Bearer.

Its not clear what you mean about MD5. Do you have a specific auth
helper like NCSA storing passwords using that hash?
