## HTTPS
HTTPS, which stands for *hypertext transfer protocol secure*, is an extension of the HTTP protocol. As its name suggests, it adds a layer of security to the data exchanged between client and server. By adding an encryption layer to the exchanged packets, it seeks to avoid man-in-the-middle attacks, eavesdropping, etc.
HTTPS, which stands for *hypertext transfer protocol secure*, is an extension of the HTTP protocol. As its name suggests, it adds a layer of security to the data exchanged between client and server. By adding an encryption layer to the exchanged packets, it seeks to avoid man-in-the-middle attacks, eavesdropping, etc. While HTTP uses port 80 by default, HTTPS uses port 443.
As part of its bigger goal to "encrypt the entire Internet", the [Electronic Frontier Foundation](https://certbot.eff.org/about/) developed Certbot, a free and open source tool for automating the server-side deployment of [Let's Encrypt Certificates](https://letsencrypt.org/), thus enabling HTTPS.

```bash
$ sudo certbot certonly -d myserver.org

After following the process, and if all went well, you should now see the following message:
```
- Congratulations! Your certificate and chain have been saved at:
/etc/letsencrypt/live/mydomain.org/fullchain.pem
Your key file has been saved at:
/etc/letsencrypt/live/mydomain.org/privkey.pem
Your cert will expire on 2019-09-24. To obtain a new or tweaked
version of this certificate in the future, simply run certbot
again. To non-interactively renew *all* of your certificates, run
"certbot renew"

Now, it is time to edit your etc/apache2/sites-available/mydomain.conf file accordingly:
In case you didn't notice, there is now an if statement that evaluates true in case a certain module is present. In this case, it evaluates to true if [mod_ssl](http://www.modssl.org/) is present. [Apache modules](https://en.wikipedia.org/wiki/List_of_Apache_modules) can be installed as following:
```bash
$ sudo a2enmod modulename
```
To verify which modules are already running on your server, type:
```bash
$ sudo apache2ctl -M
```
If the required ssl_module is not listed, run:
```bash
$ sudo a2enmod ssl
```
Time to restart Apache and load all of these changes!
## index.html
At this point, when typing https://mydomain.org into your browser, you're greeted with a page that looks a little something like this:
![Default apache on debian index.html page](http://assets.digitalocean.com/how-to-install-lamp-debian-9/small_apache_default_debian9.png)
If you cd into your /var/www/html folder, you will find this default index.html. As recommended by this page itself, you should edit this file before continuing operations on your webserver.
Open it on your favourite text editor and let's get started on a bare-bones "Hello Homebrew World"! webpage.
```html
<!doctype html>
<htmllang="en">
<head>
<metacharset="utf-8">
<title>My first homebrewed webpage</title>
</head>
<body>
<h1>Hello Homebrew World!</h1>
</body>
</html>
```
Open your browser again and savour the fruits of your hard work.
That was it! Now you are ready to have hours of endless fun sailing the vast sea of HTML, CSS, JavaScript, etc.
