ntroduction
 
  
−
TLS, or transport layer security, and its predecessor SSL, secure sockets layer, are secure protocols created in order to place normal traffic in a protected, encrypted wrapper.
+
Agar komunikasi dapat dilakukan dengan aman kita perlu meng-enkripsi komunikasi menggunakan TLS/SSL. Berikut ini adalah caranya di Ubuntu 16.04.
  
−
These protocols allow traffic to be sent safely between remote parties without the possibility of the traffic being intercepted and read by someone in the middle. They are also instrumental in validating the identity of domains and servers throughout the internet by establishing a server as trusted and genuine by a certificate authority.
+
==Install Apache==
  
−
In this guide, we'll cover how to create a self-signed SSL certificate for Apache on an Ubuntu 14.04 server, which will allow you to encrypt traffic to your server. While this does not provide the benefit of third party validation of your server's identity, it fulfills the requirements of those simply wanting to transfer information securely.
+
instalasi
  
−
Note: You may want to consider using Let's Encrypt instead of a self-signed certificate. Let's Encrypt is a new certificate authority that issues free SSL/TLS certificates that are trusted in most web browsers. Check out the tutorial to get started: How To Secure Apache with Let's Encrypt on Ubuntu 14.04
+
sudo apt update
−
Prerequisites
+
sudo apt -y install apache2
  
−
Before you begin, you should have some configuration already taken care of.
 
  
−
We will be operating as a non-root user with sudo privileges in this guide. You can set one up by following steps 1-4 in our Ubuntu 14.04 initial server setup guide.
+
==Aktifkan SSL module==
  
−
You are also going to need to have Apache installed. If you don't already have that up and running, you can quickly fix that by typing:
+
enable
  
−
sudo apt-get update
+
sudo a2enmod ssl
−
sudo apt-get install apache2
 
  
−
Step One — Activate the SSL Module
+
restart apache
  
−
SSL support actually comes standard in the Ubuntu 14.04 Apache package. We simply need to enable it to take advantage of SSL on our system.
+
sudo service apache2 restart
  
−
Enable the module by typing:
 
  
−
sudo a2enmod ssl
+
==Buat Self-Signed SSL Certificate==
  
−
After you have enabled SSL, you'll have to restart the web server for the change to be recognized:
+
buat folder
  
−
sudo service apache2 restart
+
sudo mkdir /etc/apache2/ssl
  
−
With that, our web server is now able to handle SSL if we configure it to do so.
+
buat certificate
−
Step Two — Create a Self-Signed SSL Certificate
 
  
−
Let's start off by creating a subdirectory within Apache's configuration hierarchy to place the certificate files that we will be making:
+
sudo openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout /etc/apache2/ssl/apache.key -out /etc/apache2/ssl/apache.crt
  
−
sudo mkdir /etc/apache2/ssl
+
isi dengan
  
−
Now that we have a location to place our key and certificate, we can create them both in one step by typing:
+
Country Name (2 letter code) [AU]:ID
 +
State or Province Name (full name) [Some-State]:DKI
 +
Locality Name (eg, city) []:Jakarta
 +
Organization Name (eg, company) [Internet Widgits Pty Ltd]:ORGANISASI-ANDA
 +
Organizational Unit Name (eg, section) []:RND
 +
Common Name (e.g. server FQDN or YOUR name) []:organisasi-anda.id
 +
Email Address []:onno@organisasi-anda.id
  
−
sudo openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout /etc/apache2/ssl/apache.key -out /etc/apache2/ssl/apache.crt
+
Beberapa informasi tambahan
  
−
Let's go over exactly what this means.
+
* openssl: This is the basic command line tool provided by OpenSSL to create and manage certificates, keys, signing requests, etc.
 +
* req: This specifies a subcommand for X.509 certificate signing request (CSR) management. X.509 is a public key infrastructure standard that SSL adheres to for its key and certificate managment. Since we are wanting to create a new X.509 certificate, this is what we want.
 +
* -x509: This option specifies that we want to make a self-signed certificate file instead of generating a certificate request.
 +
* -nodes: This option tells OpenSSL that we do not wish to secure our key file with a passphrase. Having a password protected key file would get in the way of Apache starting automatically as we would have to enter the password every time the service restarts.
 +
* -days 365: This specifies that the certificate we are creating will be valid for one year.
 +
* -newkey rsa:2048: This option will create the certificate request and a new private key at the same time. This is necessary since we didn't create a private key in advance. The rsa:2048 tells OpenSSL to generate an RSA key that is 2048 bits long.
 +
* -keyout: This parameter names the output file for the private key file that is being created.
 +
* -out: This option names the output file for the certificate that we are generating.

When you hit "ENTER", you will be asked a number of questions.
+
==Konfigurasi apache untuk menggunakan SSL==
  
−
The most important item that is requested is the line that reads "Common Name (e.g. server FQDN or YOUR name)". You should enter the domain name you want to associate with the certificate, or the server's public IP address if you do not have a domain name.
+
Edit
  
−
The questions portion looks something like this:
+
cd /etc/apache2/sites-available
 +
cp default-ssl.conf default-ssl.conf.asli
 +
sudo vi /etc/apache2/sites-available/default-ssl.conf

−
Common Name (e.g. server FQDN or YOUR name) []:your_domain.com
 
−

This may look a bit complicated, but luckily, we don't need to worry about most of the options here.
+
enable
  
−
We want to set the normal things we'd configure for a virtual host (ServerAdmin, ServerName, ServerAlias, DocumentRoot, etc.) as well as change the location where Apache looks for the SSL certificate and key.
+
sudo a2ensite default-ssl.conf
−
 
 
−
In the end, it will look something like this. The entries in red were modified from the original file:
 
−
 
 
−
<IfModule mod_ssl.c>
 
−
    <VirtualHost _default_:443>
 
−
        ServerAdmin admin@example.com
 
−
        ServerName your_domain.com
 
−
        ServerAlias www.your_domain.com
 
−
        DocumentRoot /var/www/html
 
−
        ErrorLog ${APACHE_LOG_DIR}/error.log
 
−
        CustomLog ${APACHE_LOG_DIR}/access.log combined
 
−
        SSLEngine on
 
−
        SSLCertificateFile /etc/apache2/ssl/apache.crt
 
−
        SSLCertificateKeyFile /etc/apache2/ssl/apache.key
 
−
        <FilesMatch "\.(cgi|shtml|phtml|php)$">

                        downgrade-1.0 force-response-1.0
 
−
        BrowserMatch "MSIE [17-9]" ssl-unclean-shutdown
 
−
    </VirtualHost>
 
−
</IfModule>
 
−
 
 
−
Save and exit the file when you are finished.
 
−
Step Four — Activate the SSL Virtual Host
 
−
 
 
−
Now that we have configured our SSL-enabled virtual host, we need to enable it.
 
−
 
 
−
We can do this by typing:
 
−
 
 
−
sudo a2ensite default-ssl.conf
 
−
 
 
−
We then need to restart Apache to load our new virtual host file:
 
−
 
 
−
sudo service apache2 restart
 
−
 
 
−
This should enable your new virtual host, which will serve encrypted content using the SSL certificate you created.
 
−
Step Five — Test your Setup
 
−
 
 
−
Now that you have everything prepared, you can test your configuration by visiting your server's domain name or public IP address after specifying the https:// protocol, like this:
 
−
 
 
−
https://server_domain_name_or_IP
 
−
 
 
−
You will get a warning that your browser cannot verify the identity of your server because it has not been signed by one of the certificate authorities that it trusts.
 
−
 
 
−
apache ssl warning
 
−
 
 
−
This is expected since we have self-signed our certificate. While our certificate will not validate our server for our users because it has had no interaction with a trusted certificate authority, it will still be able to encrypt communication.
 
−
 
 
−
Since this is expected, you can hit the "Proceed anyway" button or whatever similar option you have in your browser.
 
−
 
 
−
You will now be taken to content in the DocumentRoot that you configured for your SSL virtual host. This time your traffic is encrypted. You can check this by clicking on the lock icon in the menu bar:
 
−
 
 
−
apache ssl encrypted
 
−
 
 
−
You can see in the middle green section that the connection is encrypted.
 
−
Conclusion
 
−
 
 
−
You should now have SSL enabled on your website. This will help to secure communication between visitors and your site, but it will warn each user that the browser cannot verify the validity of the certificate.
 
−
 
 
−
If you are planning on launching a public site and need SSL, you will be better off purchasing an SSL certificate from a trusted certificate authority.

Agar komunikasi dapat dilakukan dengan aman kita perlu meng-enkripsi komunikasi menggunakan TLS/SSL. Berikut ini adalah caranya di Ubuntu 16.04.

Install Apache

instalasi 

sudo apt update
sudo apt -y install apache2


Aktifkan SSL module

enable 

sudo a2enmod ssl

restart apache 

sudo service apache2 restart


Buat Self-Signed SSL Certificate

buat folder 

sudo mkdir /etc/apache2/ssl

buat certificate 

sudo openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout /etc/apache2/ssl/apache.key -out /etc/apache2/ssl/apache.crt

isi dengan 

Country Name (2 letter code) [AU]:ID
