 With that, your self-signed SSL certificate is all set. You can now test that your server is correctly encrypting its traffic.
+===== Step 5 — Testing Encryption =====
+You’re now ready to test your SSL server.
+Open your web browser and type <code bash>https://</code> followed by your server’s domain name or IP into the address bar:
+<code bash>https://server_domain_or_IP</code>
+Because the certificate you created isn’t signed by one of your browser’s trusted certificate authorities, you will likely see a scary looking warning like the one below:Apache self-signed cert warningThis is expected and normal. We are only interested in the encryption aspect of our certificate, not the third party validation of our host’s authenticity. Click ADVANCED and then the link provided to proceed to your host anyways:Apache self-signed override
+You should be taken to your site. If you look in the browser address bar, you will see a lock with an « x » over it or another similar “not secure” notice. In this case, this just means that the certificate cannot be validated. It is still encrypting your connection.
+If you configured Apache to redirect HTTP to HTTPS, you can also check whether the redirect functions correctly:
+<code bash>http://server_domain_or_IP</code>
+If this results in the same icon, this means that your redirect worked correctly. However, the redirect you created earlier is only a temporary redirect. If you’d like to make the redirection to HTTPS permanent, continue on to the final step.
+===== Step 6 — Changing to a Permanent Redirect =====
+If your redirect worked correctly and you are sure you want to allow only encrypted traffic, you should modify the unencrypted Apache Virtual Host again to make the redirect permanent.
+Open your server block configuration file again:
+<code bash>sudo nano /etc/apache2/sites-available/000-default.conf</code>
+Find the Redirect line we added earlier. Add permanent to that line, which changes the redirect from a 302 temporary redirect to a 301 permanent redirect:
+**/etc/apache2/sites-available/000-default.conf**
+<code bash><VirtualHost *:80>
+        . . .
+        Redirect permanent "/" "https://your_domain_or_IP/"
+        . . .
+</VirtualHost></code>
+Save and close the file.
+Check your configuration for syntax errors:
+<code bash>sudo apache2ctl configtest</code>
+If this command doesn’t report any syntax errors, restart Apache:
+<code bash>sudo systemctl restart apache2</code>
+This will make the redirect permanent, and your site will only serve traffic over HTTPS.
