Digest the current input message stream of the specified length.
IppStatus ippsDAARijndael256Update(const Ipp8u *pSrcMesg, int mesglen, IppsDAARijndael256State* pCtx);
pSrcMesg |
Pointer to the buffer containing a part or the whole message. |
mesglen |
Length of the actual part of the message in bytes. |
pCtx |
Pointer to the IppsDAARijndael256State context. |
This function is declared in the ippcp.h file. The function digests the current input message stream of the specified length. The function first integrates the previous partial message block with the input message stream, and then partitions them into multiple message blocks (as specified by applied hash algorithm) with a possible additional partial block. For each message block, the function uses the selected block cipher to transform the block of plaintext into a new chaining digest value.
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. |
ippStsContextMatchErr |
Indicates an error condition if the context parameter does not match the operation. |
