In case you'd like to use an SSL Certificate for your site, so as to protect the payment and login information that users send, you will need a Certificate Signing Request, or CSR. The Request contains all the information for the entity which will use the SSL in an encoded form, such as the exact web address for the site, the Business/Organization name, physical and e-mail address. It has to be sent to a vendor, or Certificate Authority, which reviews the posted data and depending on it, gives the SSL certificate. The SSL set up requires four bits of code - the certificate, the CSR, a special private key that's generated together with the CSR and the SSL vendor private key. A website that has an SSL installed can be accessed with https:// instead of the usual http:// and the info submitted for the CSR can be viewed in standard text format through a web browser.
