Computes MD5 digest value of the input message.
IppStatus ippsMD5MessageDigest(const Ipp8u *pMsg, int len, Ipp8u *pMD);
ippcp.h
pMsg |
Pointer to the input message. |
len |
Message length in octets. |
pMD |
Pointer to the resultant digest. |
The function uses the selected hash algorithm to compute digest value of the entire (non-streaming) input message.
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. |
The code example below shows 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);
}
