# By default, this playbook automatically retrieves and auto-renews
# free SSL certificates from Let's Encrypt.
#
# The following retrieval methods are supported:
# - "lets-encrypt" - the playbook obtains free SSL certificates from Let's Encrypt
# - "self-signed" - the playbook generates and self-signs certificates
# - "manually-managed" - lets you manage certificates by yourself (manually; see below)
# - "none" - like "manually-managed", but doesn't care if you don't drop certificates in the location it expects
#
# If you decide to manage certificates by yourself (`matrix_ssl_retrieval_method: manually-managed`),
# you'd need to drop them into the directory specified by `matrix_ssl_config_dir_path`
# obeying the following hierarchy:
# - <matrix_ssl_config_dir_path>/live/<domain>/fullchain.pem
# - <matrix_ssl_config_dir_path>/live/<domain>/privkey.pem
# where <domain> refers to the domains that you need (usually `matrix_server_fqn_matrix` and `matrix_server_fqn_element`).
#
# The "none" type (`matrix_ssl_retrieval_method: none`), simply means that no certificate retrieval will happen.
# It's useful for when you've disabled the nginx proxy (`matrix_nginx_proxy_enabled: false`)
# and you'll be using another reverse-proxy server (like Apache) with your own certificates, managed by yourself.
# It's also useful if you're using `matrix_nginx_proxy_https_enabled: false` to make this nginx proxy serve
# plain HTTP traffic only (usually, on the loopback interface only) and you'd be terminating SSL using another reverse-proxy.

# Nginx Optimize SSL Session
#
# ssl_session_cache:
# - Creating a cache of TLS connection parameters reduces the number of handshakes
#   and thus can improve the performance of application.
# - Default session cache is not optimal as it can be used by only one worker process
#   and can cause memory fragmentation. It is much better to use shared cache.
# - Learn More: https://nginx.org/en/docs/http/ngx_http_ssl_module.html
#
# ssl_session_timeout:
# - Nginx by default it is set to 5 minutes which is very low.
#   should be like 4h or 1d but will require you to increase the size of cache.
