If you'd like to use an SSL Certificate on your website, in order to protect the payment and login information which users send, you'll need a Certificate Signing Request, also known as CSR. The Request contains all the information related to the entity that will use the SSL in an encoded form, such as the exact web 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 submitted info and based on it, issues the SSL certificate. The SSL set up requires 4 bits of code - the certificate, the CSR, a unique private key that is generated alongside the CSR and the SSL vendor private key. A website which 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 via a web browser.
