In case you wish to use an SSL Certificate for your website, in order 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 encoded form, for instance the exact website address for the site, the Business/Organization name, physical and email address. It should be submitted to a service provider, or Certificate Authority, which reviews the submitted information and based on it, gives the SSL certificate. The actual SSL set up requires four different bits of code - the certificate, the CSR, a specific 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 from a web browser.
