CMS_DH_KEY_INFO structure (wincrypt.h)

The CMS_DH_KEY_INFO structure is used with the KP_CMS_DH_KEY_INFO parameter in the CryptSetKeyParam function to contain Diffie-Hellman key information.

Syntax

typedef struct _CMS_DH_KEY_INFO {
  DWORD           dwVersion;
  ALG_ID          Algid;
  LPSTR           pszContentEncObjId;
  CRYPT_DATA_BLOB PubInfo;
  void            *pReserved;
} CMS_DH_KEY_INFO, *PCMS_DH_KEY_INFO;

Members

dwVersion

The size, in bytes, of this structure.

Algid

One of the ALG_ID values that identifies the algorithm for the key to be converted.

pszContentEncObjId

The address of a null-terminated ANSI string that contains the object identifier (OID) of the content encryption algorithm.

PubInfo

A CRYPT_DATA_BLOB structure that contains additional public information. This member is optional and the cbData member of this structure can be zero if this is not needed.

pReserved

Reserved for future use and must be NULL.
