In case you offer products and services on your website and you'd like the payment details that customers upload to be risk-free, you should use an SSL certificate. Secure Sockets Layer is a protocol that encrypts the data exchanged between a user and a server, but to receive an SSL, you'll need a Certificate Signing Request (CSR). This is Base64 encoded info that the SSL service provider will use to issue the certificate. The CSR contains the web address, Business name and Unit, postal address and email of the entity which will use the certificate. The Certificate Authority reviews and authorizes the CSR before it supplies an SSL certificate that is signed in an electronic format with its private key as an authority. In order to set up an SSL, you'll need an overall of four batches of code - the CSR, a Private Key that is created once you generate the Request, the actual certificate as well as a specific Certificate Authority code, that's unique for each and every vendor.
