If you offer services and products on your website and you would like the payment details that customers upload to be risk-free, you will need an SSL certificate. Secure Sockets Layer is a protocol which encrypts the info exchanged between a user and a server, but to acquire an SSL, you'll need a Certificate Signing Request (CSR). This is Base64 encoded info that the SSL vendor will use to create the certificate. The CSR includes the web address, Business name and Unit, mailing address and e-mail of the organization that will use the certificate. The Certificate Authority studies and authorizes the CSR before it supplies an SSL certificate which is signed electronically with its private key as an authority. In order to install an SSL, you will need a total of 4 batches of code - the CSR, a Private Key that is made once you generate the Request, the actual certificate and a specific Certificate Authority code, that is unique for every single vendor.
