Simply put, those of you who have an eshop or anyway an informational site, you have been asked (especially in the last 2 years) to change your site's access address protocol from http://tositesas.gr σε https://tositesas.gr

The difference between http and https is that the connection between the visitor's computer and the site hosting your site is encrypted.

This means that the visitor/customer feels more secure.

As you now understand, there must be https, because no one wants http and browsers chrome, firefox, etc. they issue a warning that kicks the visitor off your site in record time.

How to install it for free on your Ubuntu Server or shared hosting server

• In the case of a shared hosting server (cpanel, plesk etc) there is probably already free SSL, so all you have to do is visit the site address with https:// in front to try it.
• If not....... then connect your site's domain with the free service https://cloudflare.com and get ssl from there as well as absolute protection against hacking attacks (ddos etc)

Now let's go to the case where you have a virtual private hosting space (virtual private server or otherwise VPS):

First of all, how you can set up your own VPS on Google services, see here: https://nicolaslagios.com/οδηγίες-google-cloud-server-δωρεάν-για-1-χρόνο-ρυθμίσε/

So how do you add SSL for free:

sudo add-apt-repository ppa:certbot/certbot

(press enter to accept)

sudo apt install python-certbot-apache

systemctl reload apache2

If the command: sudo ufw status is inactive then proceed to the next step, if not then: sudo ufw allow 'Apache Full' and sudo ufw delete allow 'Apache'

sudo certbot --apache -d your_domain -d www.your_domain

(where it says your_domain change it to the site address)
