SSL certificates

You can use any SSL certificates, you can buy from Thawte, VeriSign etc. But you can also create and sign your own server certificates. A good documentation on how to do this can be found here:

SSL with mod_ssl for apache

If you use mod_ssl for apache, the following hints and configurations might be helpful to you.

SSL with virtual hosts

If you can't or don't want to assign a separate ip to every kOOL installation on your server, you can still use SSL encryption for every virtual host by using different ports. The following configuration shows a possible setup with a permanent redirect to the https url.

Make apache listen on port 80 AND 1443

Listen 80

<IfModule mod_ssl.c>
Listen 1443

</ifModule>

Add a permanent redirect to the https url

<VirtualHost ip.of.your.server:80>
ServerName your.kool.com
Redirect permanent / https://your.kool.com:1443
</VirtualHost>

Add the SSL settings to your virtual host configuration

<IfModule mod_ssl.c>
<VirtualHost ip.of.your.server:1443>
    ServerAdmin webmaster@your.kool.com
    DocumentRoot /var/www/kOOL_demo
    ServerName your.kool.com
    ScriptAlias /fileshare/cgi/ /var/www/kOOL_demo/fileshare/cgi/

    SSLEngine on
    SSLCertificateFile /etc/apache/ssl.crt/kOOL-demo.cert.pem
    SSLCertificateKeyFile /etc/apache/ssl.key/kOOL-demo.key.pem

</VirtualHost>

</IfModule>
