In case you offer services and goods on your website and you would like the payment data that clients submit to be risk-free, you'll need an SSL certificate. Secure Sockets Layer is a protocol that encodes the info exchanged between a user and a web server, but in order to obtain an SSL, you need a Certificate Signing Request (CSR). This is Base64 encoded info that the SSL supplier will use to create the certificate. The CSR contains your website address, Business name and Unit, postal address and email of the entity which will use the certificate. The Certificate Authority reviews and approves the CSR before it supplies an SSL certificate that is signed digitally using its private key as an authority. To be able to install an SSL, you need an overall of four batches of code - the CSR, a Private Key that is created after you generate your Request, the actual certificate and a special Certificate Authority code, that's unique for each vendor.
