HMAC_Final¶
Completes computation of the HMAC value.
Syntax¶
IppStatus ippsHMAC_Final(Ipp8u *pMD, int mdLen, IppsHMACState *pCtx);
IppStatus ippsHMACFinal_rmf(Ipp8u *pMD, int mdLen, IppsHMACState_rmf *pCtx);
Include Files¶
ippcp.h
Parameters¶
pMD |
Pointer to the resultant HMAC value. |
mdLen |
Specified HMAC length. |
pCtx |
Pointer to the IppsHMACState or IppsHMACState_rmf context. |
Description¶
The function completes calculation of the digest value and stores the result at the memory location specified by pMD.
Note
This function has a reduced memory footprint version. To learn more, see Reduced Memory Footprint Functions.
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. |
ippStsContextMatchErr |
Indicates an error condition if the context parameter does not match the operation. |
ippStsLengthErr |
Indicates an error condition if mdLen is less than one or greater than the length of the hash value. |
