Already the Public Key does not need to be secret and should be placed on CSR (Certificate Signing Request) which is a data file containing the details of the site and the company and this must be submitted through the application form and your data will be validated and are correct. So your digital certificate will be issued.

Your web server will associate the certificate with its private key. Your server will establish an encrypted link between your website and the browser on your consumer.

So if the website begins with https: // instead of http: //, it means you landed on a secure website.

Currently 99% of browsers are able to connect to a web server using http or https and the main browsers Internet Explorer or Firefox. In these two cases are shown a golden padlock that indicates that you are accessing a secure website. This lock only appears when a digital certificate is installed on the web server.
