Install a self-signed certificate for testing HTTPS/SSL

U should create  three files:

•  a self-signed certificate file (ssl-cert.crt), which  is used by Browser.
•  a public key file(ssl-cert.pfx) with proof of identity for signed and/or encrypted message, which  is used by Browser. The public key can be derived from its corresponding private key.
• a privet key file(ssl-cert-private.key),  which is used by Apache.

How to Create the SSL X.509 Certificates? 


 Import certificate into Google Chrome (other browsers - try to figure it out on your own):

• Go to Preferences, click "Under the hood".
• Under HTTPS/SSL, click on "Manage Certificates".
• Click "Import..." and import your ssl-cert.pfx file. Your certificate should appear now in the list of "Your Certificates".
• Go to "Authorities", click "Import.." and import your ssl-cert.crt file. The name should now appear under the list of Authorities.

Configure Apache to work with SSL

• Execute: 

           sudo cp ssl-cert.crt /etc/ssl/certs; 

           sudo cp ssl-cert-private.key /etc/ssl/private/ 

           sudo a2enmod ssl

           cd /etc/apache2/sites-enabled/; 

           sudo ln -s ../sites-available/default-ssl 000-default-ssl

• Edit /etc/apache2/sites-available/

default-ssl, and replace the following lines:         SSLCertificateFile    /etc/ssl/certs/ssl-cert-



snakeoil.pem
        SSLCertificateKeyFile /etc/ssl/private/ssl-cert-



snakeoil.key

• With the following lines:

       #SSLCertificateFile    /etc/ssl/certs/ssl-cert-



snakeoil.pem
         SSLCertificateFile /etc/ssl/certs/ssl-cert.crt
      #SSLCertificateKeyFile /etc/ssl/private/ssl-cert-



snakeoil.key
        SSLCertificateKeyFile /etc/ssl/private/ssl-cert-



private.key 

• Restart Apache by executing the following command: 

        sudo service apache2 restart 

Now when you access the website your certificate should be valid.
