IppStatus ippsDAARijndael192MessageDigest(const Ipp8u *pSrcMsg, int msgLen, const Ipp8u *pKey, IppsRijndaelKeyLength keyLen, Ipp8u *pDAC, int macLen);

Parameters

pSrcMsg

Pointer to the input message.

msgLen

Message length in bytes.

pKey

Pointer to the user-supplied key.

keyLen

Key length.

pMAC

Pointer to the resultant HMAC value.

macLen

Specified HMAC length.

Description

This function is declared in the ippcp.h file. The function takes the input key pKey of the specified key length keyLen and applied keyed hash-based message authentication code scheme to transform the input message into the respective message authentication code pMAC of the specified length macLen.

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 msgLen is less than zero, macLen is less than 1 or greater than cipher's data block length, keyLen value is illegal.
