CSR creation in IIS 8 & 8.5

The CSR file contains information that will be used to create your certificate.

A certificate signing request (CSR) is one of the first steps towards getting your SSL certificate. We recommend to generate it on the same server you plan to install the certificate on, since the process will create the Private Key as well, which is needed during the SSL Certificate installation process.
