Pointer to the uninitialized hash method.

The ippsHashMethodSet_MD5 function is deprecated. The MD5 algorithm is considered weak due to known attacks on it. The functionality remains in the library, but the implementation will no longer be optimized and no security patches will be applied.

Each of these functions accepts a pointer to uninitialized memory of the size obtained using HashMethodGetSize, and initializes this memory to method-defined implementation of a particular hash algorithm. Use these functions in calls to HashInit and HashMessage.

Return Values


Indicates no errors. Any other value indicates an error or warning.


Indicates an error condition if any of the specified pointers is NULL.
