MD5MessageDigest
MD5MessageDigest
Computes MD5 digest value of the input message (deprecated).
Syntax
IppStatus ippsMD5MessageDigest(const Ipp8u *
pMsg
, int
len
, Ipp8u *
pMD
);
Include Files
ippcp.h
Parameters
- pMsg
- Pointer to the input message.
- len
- Message length in octets.
- pMD
- Pointer to the resultant digest.
Description
This 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.
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 isNULL.
- ippStsLengthErr
- Indicates an error condition if the input data stream length is less than zero.
Example
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);
}
