In case you would like to use an SSL Certificate for your website, in order to protect the payment and login data which users submit, you will need a Certificate Signing Request, or CSR. The Request contains all the information about the entity which will use the SSL in an encrypted form, for example the exact website address for the website, the Business/Organization name, physical and email address. It has to be sent to a vendor, or Certificate Authority, which reviews the submitted information and based 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 alongside the CSR and the SSL vendor private key. A website that has an SSL installed can be accessed with https:// rather than the usual http:// and the info submitted for the CSR will be viewed in standard text format through an Internet browser.
