In case you would like to use an SSL Certificate for your site, to protect the payment and login data which users post, you will need a Certificate Signing Request, also known as CSR. The Request contains all the info for the entity that will use the SSL in an encoded form, for instance the exact web address for the site, the Business/Organization name, physical and e-mail address. It has to be sent to a service provider, or Certificate Authority, which reviews the posted data and depending on it, gives the SSL certificate. The actual SSL installation requires 4 bits of code - the certificate, the CSR, a special private key which is generated alongside the CSR and the SSL vendor private key. A site which has an SSL installed can be loaded with https:// instead of the usual http:// and the info submitted for the CSR will be viewed in standard text format via an Internet browser.
