CryptSetKeyIdentifierProperty function (wincrypt.h)

Important  This API is deprecated. New and existing software should start using Cryptography Next Generation APIs. Microsoft may remove this API in future releases.
 
The CryptSetKeyIdentifierProperty function sets the property of a specified key identifier. This function can set the property on the computer identified in pwszComputerName.

Syntax

BOOL CryptSetKeyIdentifierProperty(
  [in]  const CRYPT_HASH_BLOB *pKeyIdentifier,
  [in]  DWORD                 dwPropId,
  [in]  DWORD                 dwFlags,
  [in]  LPCWSTR               pwszComputerName,
  [in]  void                  *pvReserved,
  [out] const void            *pvData
);

Parameters

[in] pKeyIdentifier

A pointer to a CRYPT_HASH_BLOB containing the key identifier.

[in] dwPropId

Identifies the property to be set. The value of dwPropId determines the type and content of the pvData parameter. Any certificate property ID can be used. CERT_KEY_PROV_INFO_PROP_ID is the property of most interest.

[in] dwFlags

The following flags can be set. They can be combined with a bitwise-OR operation.

Value Meaning
CRYPT_KEYID_MACHINE_FLAG
Sets the property of the LocalMachine (if pwszComputerName is NULL) or remote computer (if pwszComputerName is not NULL). For more information, see pwszComputerName.
CRYPT_KEYID_DELETE_FLAG
The key identifier and all of its properties are deleted.
CRYPT_KEYID_SET_NEW_FLAG
Sets a new key identifier property. If the property already exists, the attempt fails, and FALSE is returned with the last error code set to CRYPT_E_EXISTS.

[in] pwszComputerName

A pointer to a null-terminated string that contains the name of a remote computer that has the key identifier where the properties are set. If CRYPT_KEYID_MACHINE_FLAG flag is set, searches the remote computer for a list of key identifiers. If the local computer is to be set and not a remote computer, set pwszComputerName to NULL.

[in] pvReserved

Reserved for future use and must be NULL.

[out] pvData

If dwPropId is CERT_KEY_PROV_INFO_PROP_ID, pvData points to a CRYPT_KEY_PROV_INFO structure containing the property of the key identifier.

If dwPropId is not CERT_KEY_PROV_INFO_PROP_ID, pvData points to a CRYPT_DATA_BLOB structure containing the property of the key identifier.

Setting pvData to NULL deletes the property.

Return value

If the function succeeds, the return value is nonzero (TRUE).

If the function fails, the return value is zero (FALSE). For extended error information, call GetLastError.

Note  If CRYPT_KEYID_SET_NEW_FLAG is set and the property already exists, FALSE is returned with the last error code set to CRYPT_E_EXISTS.
