In case you would like to use an SSL Certificate on your website, to protect the payment and login information which users submit, you will need a Certificate Signing Request, also known as CSR. The Request contains all the information related to the entity which will use the SSL in an encoded form, for example the exact website address for the site, the Business/Organization name, physical and email address. It has to be sent to a vendor, or Certificate Authority, which reviews the provided information and depending on it, gives the SSL certificate. The actual SSL installation requires four different bits of code - the certificate, the CSR, a specific private key that's generated together with the CSR and the SSL vendor private key. An Internet site that has an SSL installed can be opened with https:// rather than the usual http:// and the information submitted for the CSR can be viewed in standard text format via an Internet browser.
