Introduction
In this tutorial I will help you to create an SSL certificate, using Nginx and Certbot on Ubuntu.
SSL Certificates protect your sensitive information such as credit card information, usernames, passwords...
Nginx is a free, open-source, high-performance HTTP server.
Certbot is a free, open-source software tool for automatically using Let’s Encrypt certificates on manually-administrated websites to enable HTTPS.
Requirements
Nginx
Ubuntu
Comfort with command Line/Terminal
Installation
1- Login To Your Server
$ ssh username@YOUR_SERVER_IP
2- Add Certbot PPA
$ sudo apt-get update
$ sudo apt-get install software-properties-common
$ sudo add-apt-repository universe
$ sudo add-apt-repository ppa:certbot/certbot
$ sudo apt-get update
3- Install Certbot
$ sudo apt-get install certbot python-certbot-nginx
4- Generate the certificate
$ sudo certbot --nginx
Choose your domaine
[sudo] password for username:
Saving debug log to /var/log/letsencrypt/letsencrypt.log
Plugins selected: Authenticator nginx, Installer nginx
Which names would you like to activate HTTPS for?

Select the appropriate numbers separated by commas and/or spaces, or leave input
blank to select all options shown (Enter 'c' to cancel): 1
Choose whether or not to redirect HTTP traffic to HTTPS.
Please choose whether or not to redirect HTTP traffic to HTTPS, removing HTTP access.

1: No redirect - Make no further changes to the webserver configuration.
2: Redirect - Make all requests redirect to secure HTTPS access. Choose this for
new sites, or if you're confident your site works on HTTPS. You can undo this
change by editing your web server's configuration.

Select the appropriate number [1-2] then [enter] (press 'c' to cancel): 2
Successfully issued
Congratulations! You have successfully enabled https://yourdomaine.com
You should test your configuration at:

IMPORTANT NOTES:
- Congratulations! Your certificate and chain have been saved at:
/etc/letsencrypt/live/yourdomaine.com-0001/fullchain.pem
Your key file has been saved at:
/etc/letsencrypt/live/yourdomaine.com-0001/privkey.pem
Your cert will expire on 2020-04-14. To obtain a new or tweaked
version of this certificate in the future, simply run certbot again
with the "certonly" option. To non-interactively renew *all* of
your certificates, run "certbot renew"
- If you like Certbot, please consider supporting our work by:
Donating to ISRG / Let's Encrypt: https://letsencrypt.org/donate
Donating to EFF: https://eff.org/donate-le
5- Test automatic renewal
$ sudo certbot renew --dry-run
Thanks for reading.

WRONG: Certbot does not create self-signed certificates. certbot uses Let's Encrypt.
