In case you need to use an SSL Certificate for your website, so as to protect the payment and login data which users send, you'll need a Certificate Signing Request, also known as CSR. The Request contains all the info related to the entity that will use the SSL in an encrypted form, for instance the exact web address for the site, the Business/Organization name, physical and e-mail address. It needs to be sent to a service provider, or Certificate Authority, which reviews the provided details and based on it, gives the SSL certificate. The actual SSL set up requires four bits of code - the certificate, the CSR, a specific private key which is 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 information submitted for the CSR will be viewed in standard text format via an Internet browser.
