If you offer goods and services on your website and you would like the payment data that people upload to be protected, you will need an SSL certificate. Secure Sockets Layer is a protocol which encodes the data exchanged between a user and a server, but in order to get an SSL, you'll need a Certificate Signing Request (CSR). This is Base64 encoded data that the SSL supplier will use to issue the certificate. The CSR features your web address, Business name and Unit, postal address and e-mail of the business that will use the certificate. The Certificate Authority reviews and authorizes the CSR before it issues an SSL certificate that is signed digitally using its private key as an authority. To be able to set up an SSL, you will need a total of four batches of code - the CSR, a Private Key that is created when you generate your Request, the actual certificate and a specific Certificate Authority code, that is unique for each vendor.
