General Definition of a Hash Function
Syntax
typedef IppStatus(_STDCALL
*IppHASH)(const Ipp8u*
pMsg
, int
msgLen
, Ipp8u*
pMD
);
Parameters
- pMsg
- Pointer to the input octet string.
- msgLen
- Length of the input string in octers.
- pMD
- Pointer to the output message digest.
Description
This declaration is included in the
ippcp.h
file. The function
calculates the digest of a non-streaming message using the implemented hash
algorithm.
Definition of a hash function used in Intel IPP
limits length (in octets) of an input message for any specific hash function by
the range of the
int
data type, with the
upper bound of 232
