[squid-users] HTTPS_PORT AND SSL CERT

[Julien TEHERY]

I retried everything possible in terms of order in the pem file.
from my workstation, if i do "openssl s_client -showcerts -connect mysquid.mycompany.com:8443" i only get one certificate/issuer, but the same command on same server but different port (apache listenning on 443), i correctly get 2 certificates/issuers:

I precise my https configuration isn't for ssl_bump purpose but only to provide secure access to the http proxy through the WAN with a valid certificate.
Do you some of you use complete certificates (including intermediate) with squid? If yes please tell me how you made it work.
I do have the latest stable squid version built with openssl support.

If squid isn't able to do that, as we  do with so many other softwares, I should consider to use an haproxy server or apache reverse proxy in front of the squid to handle correctly the SSL cert.

Regards,

Unfortunately, i've just compiled/ and built deb packages a fresh new squid 4.11
Now SSL support should be fully operational, but the certificate i still not showing the intermediate.

I just tried https_port 8443 tls-cert=/etc/squid/wildcard.mycompany.com.pem
where in the pem file i have in this precise order:


  *   cert key
  *   server cert
  *   intermediate cert

openssl client shows only the cert issuer, as it should show both.
Did I missed something ?

The experimental GnuTLS support in Debian package does not yet support
certificate chains. That is still some ways off.

For now if there is a chain with intermediate certificates you still
need to use an OpenSSL build of Squid.
