IX509ExtensionTemplateName interface

The IX509ExtensionTemplateName interface defines methods and properties that can be used to initialize or retrieve a template name extension. This extension can be placed in the certificate request to tell the certification authority what template to use when issuing or renewing a certificate. The template is identified by name.

Note  The CertificateTemplateName extension is used to identify version 1 templates. To identify a version 2 template, you can use the CertificateTemplate extension defined by the IX509ExtensionTemplate interface.
 

The extension is encoded as a name-value pair where name equals the Unicode string "CertificateTemplate" and the associated value is the name of the template. The following syntax shows an example of the Abstract Syntax Notation One (ASN.1) output for the template named "User". The extension value is encoded by using Distinguished Encoding Rules (DER).

|              ; "User"

To add this extension object to a PKCS #10 request or a CMC request, you must first add it to an IX509Extensions collection and use the collection to initialize an IX509AttributeExtensions object. For more information, see the PKCS #10 Extensions and the CMC Extensions topics.
