//  CERT_RDN Attribute Value Types

//

//  For RDN_ENCODED_BLOB, the Value's CERT_RDN_VALUE_BLOB is in its encoded

//  representation. Otherwise, its an array of bytes.

//

//  For all CERT_RDN types, Value.cbData is always the number of bytes, not

//  necessarily the number of elements in the string. For instance,

//  RDN_UNIVERSAL_STRING is an array of ints (cbData == intCnt * 4) and

//  RDN_BMP_STRING is an array of unsigned shorts (cbData == ushortCnt * 2).

//

//  For CertDecodeName, two 0 bytes are always appended to the end of the

//  string (ensures a CHAR or WCHAR string is null termi…
