How to Generate Certificate Signing Request (CSR) in Microsoft IIS 8.0


This document provides instructions for generating the Certificate Signing Request (CSR) on Internet Information Services (IIS 8). If you are unable to use these instructions for your server, RapidSSL recommends that you contact Microsoft.

NOTE: To generate a CSR, you will need to create a key pair for your server. These two items are a digital certificate key pair and cannot be separated. If you lose your public/private key file and generate a new one, your SSL Certificate will no longer match. You will have to replace the certificate then.

NOTE: All certificates that will expire after October 2013 must have a 2048 bit key size.

To generate the Certificate Signing Request (CSR) file, perform following steps:

1.   Start the IIS by selecting Tools >  Internet Information Services (IIS) Manager

2.   Select Server Certificates
