Developer Reference for Intel® Integrated Performance Primitives Cryptography
Computes SHA-256 digest value of the input message.
IppStatus ippsSHA256MessageDigest(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 the 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. |
