If you offer products and services on your website and you would like the payment data that users upload to be secure, you will need an SSL certificate. Secure Sockets Layer is a protocol which encodes the information exchanged between a user and a server, but in order to get an SSL, you need a Certificate Signing Request (CSR). This is Base64 encoded information that the SSL vendor will use to create the certificate. The CSR contains the website address, Business name and Unit, postal address and email of the business that will use the certificate. The Certificate Authority reviews and approves the CSR before it issues an SSL certificate that is signed electronically with its private key as an authority. To install an SSL, you will need a total of 4 batches of code - the CSR, a Private Key that is created when you generate your Request, the actual certificate along with a special Certificate Authority code, that is unique for each vendor.
