The object identifier for this attribute is XCN_OID_RSA_certExtensions (1.2.840.113549.1.9.14). For more information, see CERTENROLL_OBJECTID.

You must call either InitializeEncode or InitializeDecode before you can use an IX509AttributeExtensions object. The two methods complement each other. The InitializeEncode method enables you to construct an encoded Abstract Syntax Notation One (ASN.1) structure from raw data, and the InitializeDecode method enables you to initialize raw data from an encoded ASN.1 structure that contains the certificate extensions. You can call the X509Extensions property to retrieve the extensions.
