In case you need to use an SSL Certificate for your website, in order to protect the payment and login information that users send, you'll 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 website, the Business/Organization name, physical and e-mail address. It should be submitted to a vendor, or Certificate Authority, which reviews the submitted information and depending on it, gives the SSL certificate. The SSL installation requires 4 bits of code - the certificate, the CSR, a specific private key that is generated along with the CSR and the SSL vendor private key. An Internet site which has an SSL installed can be opened with https:// instead of the usual http:// and the information submitted for the CSR will be viewed in standard text format through a web browser.
