Managed PKI for SSL - Certificate Signing Request (CSR) Generation Instructions for Microsoft IIS 6.0

Description

This document provides instructions for generating a Certificate Signing Request (CSR) for Microsoft IIS 6.0. If you are unable to use these instructions for your server, Symantec recommends that you contact Microsoft. 

Symantec now offers the Symantec SSL Assistant to make it easy to generate a CSR and install a certificate for Microsoft IIS 6.0 servers running .NET 2.0 or higher.
  
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 or your password and generate a new one, your SSL Certificate will no longer match.
 
NOTE: If you are renewing a previous certificate with IIS that has a 1024 bit key length, refer to this link for steps on creating
a new CSR with a 2048 bit length without removing the previous certificate
.
 
 

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

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

  1. Click Start > All Programs > Administrative ToolsInternet Services Manager (IIS) Manager.
  2. Double-click the Server Name > Web Sites folder.
  3. Under Web Sites, right-click the corresponding Web site you wish to secure, and select Properties.


     
  4. Click Directory Security tab.
  5. Under Secure communications, click Server Certificate.


     
  6. Select Create a new certificate.


     
  7. Select Prepare the request now, but send it later.


     
  8. Enter a name for the certificate. Please note that this is not the Common Name of the certificate request.  Select the bit length of 2048 for the certificate.



    NOTE: Do not check the box for Select cryptographic service provider (CSP) for this certificate.
     
  9. Provide the Organization and the Organizational Unit information and click Next.



    Organization (O): The full legal name of your company.
    Organizational Unit (OU):  Use this field to differentiate between divisions within an organization.
  10. Provide the Common Name and click Next.



    Common Name (CN): The fully-qualified domain name to which your certificate will be issued.

    Locality or City (L): Usually the city of your organization's main office, or a main office for your organization.
  12. Provide a file name and location to save your CSR.  You will need this CSR in order to enroll for your SSL certificate.  Click Next.


     
  13. Confirm the CSR Summary Information.  Click Next > Finish.


     
  14. A CSR file has been generated. To copy and paste the information into the enrollment form, open the file in a text editor that does not add extra characters (Notepad or Vi are recommended).


     
  15. Verify your CSR using the Symantec CryptoReport.
  16. Proceed to Enrollment.

    NOTE: Upon completing the Certificate Wizard, it is important to leave the request pending for successful certificate installation.
    Choosing the option to delete the pending request from the Certificate Wizard will prevent installation of the certificate that
    is returned.
