AlternativeNameType enumeration (certenroll.h)

  • Article

The AlternativeNameType enumeration specifies the alternative name types that can be specified when initializing an IAlternativeName object. Alternative names are used to create a version 3 X.509 AlternativeNames extension. You can create this extension by using the IX509ExtensionAlternativeNames interface.

Syntax

typedef enum AlternativeNameType {
  XCN_CERT_ALT_NAME_UNKNOWN = 0,
  XCN_CERT_ALT_NAME_OTHER_NAME = 1,
  XCN_CERT_ALT_NAME_RFC822_NAME = 2,
  XCN_CERT_ALT_NAME_DNS_NAME = 3,
  XCN_CERT_ALT_NAME_X400_ADDRESS = 4,
  XCN_CERT_ALT_NAME_DIRECTORY_NAME = 5,
  XCN_CERT_ALT_NAME_EDI_PARTY_NAME = 6,
  XCN_CERT_ALT_NAME_URL = 7,
  XCN_CERT_ALT_NAME_IP_ADDRESS = 8,
  XCN_CERT_ALT_NAME_REGISTERED_ID = 9,
  XCN_CERT_ALT_NAME_GUID = 10,
  XCN_CERT_ALT_NAME_USER_PRINCIPLE_NAME = 11
} ;
