Wildcard SSL CSR Using Microsoft IIS 5.x / 6.x
Generating an IIS SSL CSR using Microsoft IIS 5.x / 6.x
A CSR is a file containing your IIS SSL certificate application information, including your Public Key.
Comodo provides a useful tool to automatically create a public/private key pair on your local machine and then use this key pair to generate a CSR and automatically submit it to Comodo over a Secure SSL connection to create your certificate for IIS 6.0.
You can then collect and automatically install the certificate onto an IIS 6.0 web server.
Or generate keys and Certificate Signing Request manually:
- Select Administrative Tools
- Start Internet Services Manager
- Open the properties window for the website the CSR is for. You can do this by right clicking on the Default Website and selecting Properties from the menu
- Open Directory Security by right clicking on the Directory Security tab
- Click Server Certificate. The following Wizard will appear:
- Click Create a new certificate and click Next.
Note: If you do not see the above screenshot, you probably already have an SSL Certificate on the website you're using. Please follow these on how to create CSR without removing the current certificate.
- Select Prepare the request and click Next.
- Provide a name for the certificate, this needs to be easily identifiable if you are working with multiple domains. This is for your records only.
- For Bit length please use 2048 and then Click Next
- Enter Organisation and Organisation Unit, these are your company name and department respectively. Click Next.
- The Common Name field should be the Fully Qualified Domain Name (FQDN) or the web address for which you plan to use your IIS SSL Certificate, e.g. the area of your site you wish customers to connect to using SSL. For example, an Instant SSL Certificate issued for comodogroup.com will not be valid for secure.comodogroup.com. If the web address to be used for SSL is secure.comodogroup.com, ensure that the common name submitted in the CSR is secure.comodogroup.com. For Wildcard SSL certificate the Common Name must contain at least one asterisks (*) Example: *.comodo.com, *.instantssl.com, etc.

Your IIS SSL Certificate will only work on this domain. Click Next when you are happy the details are absolutely correct.
- When you make your application, make sure you include the CSR in its entirety into the appropriate section of the enrollment form - including
-----BEGIN CERTIFICATE REQUEST-----to-----END CERTIFICATE REQUEST-----
