 If you are running your own Friendica site, you may want to use SSL (https) to encrypt communication between servers and between yourself and your server.

+## Web server settings

 Visit the [Mozilla's wiki](https://wiki.mozilla.org/Security/Server_Side_TLS) for instructions on how to configure a secure webserver.
 They provide recommendations for [different web servers](https://mozilla.github.io/server-side-tls/ssl-config-generator/).

+## Test your SSL settings

 When you are done, visit the test site [SSL Labs](https://www.ssllabs.com/ssltest/) to have them check if you succeeded.
+
+## Configure Friendica
+
+If you can successfully access your Friendica instance through https, there are a number of steps you can take to ensure your users will use SSL to access your instance.
+
+### Web server redirection
+
+This is the simplest way to enforce site-wide secure access.
+Every time a user tries to access any Friendica page by any mean (manual address bar entry or link), the web server issues a Permanent Redirect response with the secure protocol prepended to the requested URL.
+
+With Apache, simply add the following lines to the [code].htaccess[/code] file in the root folder of your Friendica instance (thanks to [url=https://github.com/AlfredSK]AlfredSK[/url]):
+
+[code]
+#Force SSL connections
+
+RewriteEngine On
+RewriteCond %{SERVER_PORT} 80
+RewriteRule ^(.*)$ https://your.friendica.domain/$1 [R=301,L]
+[/code]
+
+With nginx, configure your [code]server[/code] directive this way (thanks to [url=https://bjornjohansen.no/redirect-to-https-with-nginx/]Bjørn Johansen[/url]):
+
+[code]
+server {
+	listen 80;
+	listen [::]:80;
+	server_name your.friendica.domain;
+	return 301 https://$server_name$request_uri;
+}
+[/code]
+
+### SSL Settings
+
+In the Admin Settings, there are three SSL-related settings:
+- **SSL link policy**: this affects how Friendica generates internal links. If your SSL installation was successful, we recommend "Force all links to SSL" just in case your web server configuration can't be altered like described above.
+- **Force SSL**: This forces all external links to HTTPS, which may solve Mixed-Content issues, but not all websites support HTTPS yet. Use at your own risk.
+- **Verify SSL**: Enabling this will prevent Friendica to interact with self-signed SSL sites. We recommend you leave it on as a self-signed SSL certificate can be a vectorfor a man-in-the-middle attack.
