In case you offer services and goods on your website and you would like the payment info that clients send to be risk-free, you 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 obtain an SSL, you'll need a Certificate Signing Request (CSR). This is Base64 encoded data 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 organization which will use the certificate. The Certificate Authority studies and authorizes the CSR before it supplies an SSL certificate that is signed in an electronic format with its private key as an authority. To install an SSL, you need an overall of 4 batches of code - the CSR, a Private Key that is created after you generate the Request, the actual certificate and a specific Certificate Authority code, that's unique for every single vendor.
