I can't understand how SSLProtocol, SSLCipherSuite etc. are set using certbot-apache plugin

Hello,

@sahsanu @jvanasco

Thanks for your replies.

I saved my /etc/letsencrypt/ dir and removed installed certbot package from Ubuntu repositories.
I installed snapd + certbot snap package.

Now my certbot package version is 1.13.0, which is recent.

sudo certbot --version
certbot 1.13.0

I re-issued my certificates.
Now, /etc/letsencrypt/options-ssl-apache.conf is good!

# This file contains important security parameters. If you modify this file
# manually, Certbot will be unable to automatically provide future security
# updates. Instead, Certbot will print and log an error message with a path to
# the up-to-date file that you will need to refer to when manually updating
# this file.

SSLEngine on

# Intermediate configuration, tweak to your needs
SSLProtocol             all -SSLv2 -SSLv3 -TLSv1 -TLSv1.1
SSLCipherSuite          ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-CHACHA20-POLY1305:ECDHE-RSA-CHACHA20-POLY1305:DHE-RSA-AES128-GCM-SHA256:DHE-RSA-AES256-GCM-SHA384
SSLHonorCipherOrder     off
SSLSessionTickets       off

SSLOptions +StrictRequire

# Add vhost name to log entries:
LogFormat "%h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-agent}i\"" vhost_combined
LogFormat "%v %h %l %u %t \"%r\" %>s %b" vhost_common

Thanks to all of you I now understand how certbot works.
I am closing this topic.

Have a great weekend!

Cheers,
