If you would like to use an SSL Certificate for your site, to protect the payment and login info that users submit, you'll need a Certificate Signing Request, or CSR. The Request contains all the info related to the entity that will use the SSL in an encrypted form, for instance the exact website address for the site, the Business/Organization name, physical and email address. It should be submitted to a vendor, or Certificate Authority, which reviews the provided data and based on it, issues the SSL certificate. The actual SSL installation requires 4 bits of code - the certificate, the CSR, a special private key that is generated along with the CSR and the SSL vendor private key. An Internet site that has an SSL installed can be accessed with https:// instead of the usual http:// and the information submitted for the CSR will be viewed in standard text format through a web browser.
