CMC Encoded ASN.1

The following example contains a CMC request shown in ASN.1 format. The example was generated by using the Certreq.exe and Certutil.exe tools. The .inf file used as input to Certreq.exe contains the following configuration.


[NewRequest]
Subject="cn=TestCN,o=TestOrg"
RequestType=cmc

[RequestAttributes]
CertificateTemplate=User

This configuration generates the following sample output. The configuration specifies the subject, type of request (CMC), and certificate template (User). The User template specifies that:

  • The request must use either the Microsoft Base Cryptographic Provider 1.0 or the Microsoft Enhanced Cryptographic Provider 1.0.
  • The subject name must be built from Active Directory.
  • The request includes the Certificate Template Name, Enhanced Key Usage (EKU), and Key Usage extensions. The EKU extension specifies that the issued certificate can be used for Encrypting File System (EFS), secure email, and client authentication.
