Returns a status code that indicates the success or failure of the function. Windows Server 2008 R2, Windows 7, Windows Server 2008 and Windows Vista: This flag is not supported. For more information, see Creating a Hash with CNG. The object can be used for a new hashing operation immediately after calling BCryptFinishHash. If no key is used, set this parameter to zero.įlags that modify the behavior of the function. The size, in bytes, of the pbSecret buffer. This key only applies to hash algorithms opened by the BCryptOpenAlgorithmProvider function by using the BCRYPT_ALG_HANDLE_HMAC flag. The cbSecret parameter contains the size of this buffer. Windows 7: This memory management functionality is available beginning with Windows 7.Ī pointer to a buffer that contains the key to use for the hash or MAC. If the value of this parameter is zero and the value of the pbHashObject parameter is NULL, the memory for the key object is allocated and freed by this function.

The size, in bytes, of the pbHashObject buffer. Windows 7: This memory management functionality is available beginning with Windows 7. If the value of this parameter is NULL and the value of the cbHashObject parameter is zero, the memory for the hash object is allocated and freed by this function. This memory can only be freed after the handle pointed to by the phHash parameter is destroyed.

This will provide the size of the hash or MAC object for the specified algorithm. The required size of this buffer can be obtained by calling the BCryptGetProperty function to get the BCRYPT_OBJECT_LENGTH property. The cbHashObject parameter contains the size of this buffer. When you have finished using this handle, release it by passing it to the BCryptDestroyHash function.Ī pointer to a buffer that receives the hash or MAC object. This handle is used in subsequent hashing or MAC functions, such as the BCryptHashData function. The algorithm that was specified when the provider was created must support the hash interface.Ī pointer to a BCRYPT_HASH_HANDLE value that receives a handle that represents the hash or MAC object. The handle of an algorithm provider created by using the BCryptOpenAlgorithmProvider function. The BCryptCreateHash function is called to create a hash or Message Authentication Code (MAC) object.
