When you request certificates from a Windows-based enterprise certification authority (CA), you can use the Certificate Request Wizard located in the Certificates snap-in. This wizard guides you through the following steps:
Selecting the CA to which you will submit the request.
Selecting the appropriate certificate template to use for the new certificate.
Certificate templates are predefined configurations that provide common settings for the certificate request. Certificate templates describe the purpose for which the requested certificate is to be used. The list of certificate templates that is available to you is determined by the certificate types that the CA is configured to issue and whether you have been granted the access rights to the certificate template by the system administrator.
(Optional) Using Advanced Options in the Certificate Request Wizard to select the cryptographic service provider (CSP) for the key pair associated with the certificate request.
For instructions about opening and using the Certificate Request Wizard, see Request a Certificate.
You can also use the Certificate Request Wizard to request a new certificate from an enterprise CA by using an existing key pair that is already associated with another certificate.
