If you offer products and services on your website and you'd like the payment info that people upload to be protected, you should use an SSL certificate. Secure Sockets Layer is a protocol that encodes the data exchanged between a user and a web server, but in order to get an SSL, you will need a Certificate Signing Request (CSR). This is Base64 encoded info that the SSL supplier will use to create the certificate. The CSR includes your website address, Business name and Unit, postal address and e-mail of the business that will use the certificate. The Certificate Authority studies and approves the CSR before it provides an SSL certificate that is signed in an electronic format with its private key as an authority. To be able to set up an SSL, you will need an overall of four batches of code - the CSR, a Private Key that is made when you generate your Request, the actual certificate and a special Certificate Authority code, which is unique for every single vendor.
