[squid-users] squid proxy 3.5 redhat 7.3

[Madonna, A. (spir-it)]

Hello,

Due to all the documentation on the internet, we still do not have the answer to the question or whether we can use ssl_bump https traffic to intercept https traffic using a cache_peer.

So our question is, can we use ssl_bump to intercept https traffic with a parent proxy (cache_peer).

Config example:

http_port 10.**********:8080 ssl-bump cert=/etc/squid/ssl_cert/myCA.pem generate-host-certificates=on options=NO_SSLv2,NO_SSLv3,SINGLE_DH_USE,SINGLE_ECDH_USE dynamic_cert_mem_cache_size=4MB
http_port 127.0.0.1:8080 intercept ssl-bump cert=/etc/squid/ssl_cert/myCA.pem generate-host-certificates=on options=NO_SSLv2,NO_SSLv3,SINGLE_DH_USE,SINGLE_ECDH_USE dynamic_cert_mem_cache_size=4MB
https_port 127.0.0.1:8081 intercept ssl-bump cert=/etc/squid/ssl_cert/myCA.pem generate-host-certificates=on options=NO_SSLv2,NO_SSLv3,SINGLE_DH_USE,SINGLE_ECDH_USE dynamic_cert_mem_cache_size=4MB
sslcrtd_program /usr/lib64/squid/ssl_crtd -s /var/lib/ssl_db -M 4MB
sslcrtd_children 32 startup=5 idle=1
acl step1 at_step SslBump1

ssl_bump peek step1
