+
+apt repositories' keyrings
+==========================
+
+Debian family of OSes deprecated the use of `apt-key` to manage repositories' keys
+in favor of using `keyring files` which contain a binary OpenPGP format of the key
+(also known as "GPG key public ring")
+
+As nginx and passenger don't provide such key files, we created them following the
+official recomendations in their sites and install the resulting files.
+
+Nginx
+-----
+
+See https://nginx.org/en/linux_packages.html#Debian for details
+
+.. code-block:: bash
+
+   $ curl -s https://nginx.org/keys/nginx_signing.key | \
+       gpg --dearmor --output nginx-archive-keyring.gpg
+
+Phusion-passenger
+-----------------
+
+See https://www.phusionpassenger.com/docs/tutorials/deploy_to_production/installations/oss/ownserver/ruby/nginx/
+for more details.
