In case you intend to use an SSL Certificate for your website, so as to protect the payment and login data which users send, you will need a Certificate Signing Request, or CSR. The Request contains all the info about the entity which will use the SSL in an encrypted form, for example the exact web address for the site, the Business/Organization name, physical and e-mail address. It should be sent to a service provider, or Certificate Authority, which reviews the submitted info and depending on it, gives the SSL certificate. The actual SSL set up requires four bits of code - the certificate, the CSR, a unique private key that is generated together with the CSR and the SSL vendor private key. A website which 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.
