In case you'd like to use an SSL Certificate for your website, in order to protect the payment and login info that users post, you'll 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 website address for the site, the Business/Organization name, physical and email address. It should be sent to a service provider, or Certificate Authority, which reviews the provided details and based on it, issues the SSL certificate. The actual SSL set up requires four different bits of code - the certificate, the CSR, a special private key which is generated together with the CSR and the SSL vendor private key. An Internet site that 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 through an Internet browser.
