CRYPT_XML_KEY_INFO_ITEM structure (cryptxml.h)

The CRYPT_XML_KEY_INFO_ITEM structure encapsulates key information data that corresponds to a KeyInfo element. The KeyInfo element enables the recipient to obtain the key needed to validate the signature.

Syntax

typedef struct _CRYPT_XML_KEY_INFO_ITEM {
  DWORD dwType;
  union {
    LPCWSTR             wszKeyName;
    CRYPT_XML_KEY_VALUE KeyValue;
    CRYPT_XML_BLOB      RetrievalMethod;
    CRYPT_XML_X509DATA  X509Data;
    CRYPT_XML_BLOB      Custom;
  };
} CRYPT_XML_KEY_INFO_ITEM;

Members
