AES_CMACGetTag¶
Computes the MAC value of the processed part of the message.
Syntax¶
IppStatus ippsAES_CMACGetTag(Ipp8u* pMD, int mdLen, const IppsAES_CMACState *pState);
Include Files¶
ippcp.h
Parameters¶
pMD |
Pointer to the MAC value. |
mdLen |
Specified length of the MAC. |
pState |
Pointer to the IppsAES_CMACState context. |
Description¶
The function computes the MAC value based on the current context. A call to this function retains the possibility to update the MAC value.
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 mdLen is less than 1 or greater than cipher’s data block length. |
ippStsContextMatchErr |
Indicates an error condition if the context parameter does not match the operation. |
