MD5MessageDigest

Computes MD5 digest value of the input message.

Syntax

IppStatus ippsMD5MessageDigest(const Ipp8u *pSrcMesg, int mesgLen, Ipp8u *pMD);

Parameters

pSrcMesg	Pointer to the input message.
mesglen	Message length in octets.
pMD	Pointer to the resultant digest.

Description

This function is declared in the ippcp.h file. The function uses the selected hash algorithm to compute digest value of the entire (non-streaming) input message.

Return Values

ippStsNoErr	Indicates no error. Any other value indicates an error or warning.
ippStsNullPtrErr	Indicates an error condition if any of the specified pointers is NULL.
ippStsLengthErr	Indicates an error condition if the input data stream length is less than zero.

MD5 Digest of a Message

void MD5_sample(void){

   // define message

   Ipp8u msg[] = "abcdefghijklmnopqrstuvwxyz";

   // once the whole message is placed into memory,

   // one can use the integrated primitive

   Ipp8u digest[16];

   ippsMD5MessageDigest(msg, strlen((char*)msg), digest);
