OpenSSL 1.1.x & TLS 1.3

Looking under the hood, it looks like OpenSSL 1.1.1a is the default install on FreeBSD 12.0-RELEASE base. We use Squid 4.4 & Apache 2.4.37 both of which had to be recompiled.

Just a few notes if you share a similar configuration:

  • build /usr/ports/security/openssl111/ or use pkg
## modify /etc/make.conf to reflect


## modify httpd.conf to reflect something similar to these:

SSLProtocol -SSLv3 -TLSv1 -TLSv1.1 +TLSv1.2 +TLSv1.3 

Once all modifications are finalized, restart Apache and fire up to verify.

To verify with Squid, use

$ squid -v
Squid Cache: Version 4.4
Service Name: squid

This binary uses OpenSSL 1.1.1a 20 Nov 2018. For legal restrictions on distribution see

Please note the above configuration purposely disables SSLv3 & TLSv1.0-1.1 – only TLSv1.2 and 1.3 are enabled with corresponding ciphersuites. All other connections will fail.
