This structure contains a single attribute of a relative distinguished name (RDN). A whole RDN is expressed in a CERT_RDN structure that contains an array of CERT_RDN_ATTR structures.

Syntax

typedef struct _CERT_RDN_ATTR {
  LPSTR pszObjId;

  • dwValueType
    Interpretation of the Value member. The following table shows defined values for the dwValueType member and describes the corresponding structure of the Value member.

    Value Description

    CERT_RDN_ANY_TYPE

    The pszObjId member determines the assumed type and length.

    CERT_RDN_ENCODED_BLOB

    An encoded data BLOB.

    CERT_RDN_OCTET_STRING

    An arbitrary string of octets (8-bit).

    CERT_RDN_GRAPHIC_STRING

    Currently not used.

    CERT_RDN_GENERAL_STRING

    Currently not used.

    CERT_RDN_NUMERIC_STRING

    Only the characters 0 through 9 and the space character (8-bit).

    CERT_RDN_PRINTABLE_STRING

    An arbitrary string of printable characters (8-bit).

    CERT_RDN_TELETEX_STRING

    An arbitrary string of T.61 characters (8-bit).

    CERT_RDN_T61_STRING

    An arbitrary string of T.61 characters (8-bit).

    CERT_RDN_VIDEOTEX_STRING

    An arbitrary string of videotex characters.

    CERT_RDN_IA5_STRING

    An arbitrary string of IA5 (ASCII) characters.

    CERT_RDN_VISIBLE_STRING

    A 95-character set (8-bit).

    CERT_RDN_ISO646_STRING

    A 128-character set (8-bit).

    CERT_RDN_UNIVERSAL_STRING

    An array of INT4 elements (32-bit).

    CERT_RDN_INT4_STRING

    An array of INT4 elements (32-bit).

    CERT_RDN_BMP_STRING

    An array of Unicode characters (16-bit).

    CERT_RDN_UNICODE_STRING

    An array of Unicode characters (16-bit).

    CERT_RDN_UTF8_STRING

    An array of 16 bit Unicode characters UTF8 encoded on the wire as a sequence of one, two, or three 8-bit characters.

    The following table shows flags that can be combined with a bitwise OR operation into the dwValueType member.

    Value Description

    CERT_RDN_ENABLE_T61_UNICODE_FLAG

    For encoding. When set, if all the Unicode characters are <= 0xFF, the CERT_RDN_T61_STRING is selected instead of the CERT_RDN_UNICODE_STRING.

    CERT_RDN_DISABLE_CHECK_TYPE_FLAG

    For encoding. When set, the characters are not checked to see if they are valid for the value type.

    CERT_RDN_DISABLE_IE4_UTF8_FLAG

    For decoding. By default, CERT_RDN_T61_STRING encoded values are initially decoded as UTF8. If the UTF8 decoding fails, the value is decoded as 8-bit characters. If this flag is set, it skips the initial attempt to decode as UTF8 and decodes the value as 8-bit characters.

  • Value
    BLOB (Cryptography) structure containing the attribute value. The cbData member of Value is the length in bytes of the pbData member. It is not the number of elements in the pbData string.

    For example, a DWORD is 32 bits or 4 bytes long. If pbData is a pointer to a DWORD array, cbData would be four times the number of DWORD elements in the array. A short is 16 bits or 2 bytes long. If pbData is an array of short elements, cbData must be two times the length of the array.

    The pbData member of Value can be a null-terminated array of 8-bit or 16-bit characters or a fixed length array of elements. If dwValueType is set to CERT_RDN_ENCODED_BLOB, pbData is encoded.
