[squid-users] ERROR: Unsupported TLS option SINGLE_ECDH_USE

[Jonathan Lee]

Does anyone know how to activate the TLS1.3 ciphers?

Per lists.squid-cache.org <http://lists.squid-cache.org/>

Ref:
https://lists.squid-cache.org/pipermail/squid-users/2018-February/017640.html
https://openssl.org/blog/blog/2017/05/04/tlsv1.3/

And CVE-2016-0701

"Yes. Due to CVE-2016-0701 the SSL_OP_SINGLE_DH_USE option was deprecated”

It is depreciated and the new pfSense package still shows it as a default option, however how does one append 

ppending
> "TLS13-AES-256-GCM-SHA384" to the ciphers.
> 
> But the log shows the use of "ECDHE-ECDSA-AES256-GCM-SHA384”
