In case you offer services and goods on your website and you'd like the payment info that customers send to be risk-free, you need an SSL certificate. Secure Sockets Layer is a protocol that encodes the data exchanged between a user and a web server, but to get an SSL, you will need a Certificate Signing Request (CSR). This is Base64 encoded information that the SSL service provider will use to issue the certificate. The CSR includes your website address, Business name and Unit, postal address and e-mail of the business which will use the certificate. The Certificate Authority studies and authorizes the CSR before it supplies an SSL certificate which is signed in an electronic format with its private key as an authority. To be able to install an SSL, you'll need a total of 4 batches of code - the CSR, a Private Key that is made after you generate your Request, the actual certificate and a specific Certificate Authority code, that's unique for each and every vendor.
