Hi all,

 After some tunning to configure my squid's host with ssl_bump and intermediate CA (many thanks Yuri), I have tested my setup against https://www.ssllabs.com and https://howsmyssl.com and both sites returns me the following error:

Some unknown cipher suite: 0xff85 (SSLLabs says UNKNOWN (0xff85)   WEAK)
Some unknown cipher suite: 0x0081

 My relevant config is:

sslproxy_options SINGLE_DH_USE,SINGLE_ECDH_USE
sslproxy_cipher HIGH:MEDIUM:!RC4:!aNULL:!eNULL:!LOW:!3DES:!MD5:!EXP:!PSK:!SRP:!DSS
https_port 127.0.0.1:5145 intercept ssl-bump generate-host-certificates=on dynamic_cert_mem_cache_size=4MB cert=/etc/squid/certs/server.crt \
        key=/etc/squid/certs/server.key tls-dh=prime256v1:/etc/squid/certs/dhparam.pem \
                options=SINGLE_DH_USE,SINGLE_ECDH_USE cipher=HIGH:MEDIUM:!RC4:!aNULL:!eNULL:!LOW:!3DES:!MD5:!EXP:!PSK:!SRP:!DSS

 Am I doing something wrong?? I am using squid's wiki suggested config ...

Thanks.
