OsCommerce can be setup with a shared or a dedicated SSL certificate to help protect your customer's personal information.

OsCommerce Shared SSL Setup

1. Locate your configure.php file in your shopping cart folder which is in the includes folder, for example: /public_html/cart/includes/configure.php

2.  Open the file and find this series of code:

define('HTTP_SERVER', 'http://yourdomain.com'); // eg, http://localhost - should not be empty for productive servers
define('HTTPS_SERVER', 'https://yourdomain.com'); // eg, https://localhost - should not be empty for productive servers define
('ENABLE_SSL', true); // secure webserver for checkout procedure? define
('HTTP_COOKIE_DOMAIN', 'yourdomain.com'); define
('HTTPS_COOKIE_DOMAIN', 'yourdomain.com')

3. You will need to modify the HTTPS_SERVER and HTTPS_COOKIE_DOMAIN fields with your account information, and change ENABLE_SSL to "true." The format is as follows:

https://securexx.webhostinghub.com/~username

• "securexx" will be server that your account is hosted on, for example if your account is on the ehub22 server, then you would use secure22 as the server name.
• "username" is your cPanel username with Web Hosting Hub

4. Save the file, and your cart is now configured to use the shared SSL.

OsCommerce Dedicated SSL Setup

Dedicated SSL certificates are set up the same as the shared SSL, but you will use your domain name instead of the server name.  In the example below I have used Web Hosting Hub's website:

define('HTTP_SERVER', 'http://webhostinghub.com'); // eg, http://localhost - should not be empty for productive servers
define('HTTPS_SERVER', 'https://webhostinghub.com'); // eg, https://localhost - should not be empty for productive servers
define('ENABLE_SSL', true); // secure webserver for checkout procedure?
define('HTTP_COOKIE_DOMAIN', 'yourdomain.com');
define('HTTPS_COOKIE_DOMAIN', 'webhostinghub.com')

4. Save the file, and your cart is now configured to use a dedicated SSL.
