mbx_sm3_msg_digest_mb16

Computes SM3 digest values of the input messages with known length.

Syntax

mbx_status16 mbx_sm3_msg_digest_mb16(const int8u *
pa_msg[16]
, int
len[16]
, int8u *
pa_hash[16]
);
Include Files
crypto_mb/sm3.h
Parameters
pa_msg
Array of pointers to the input message.
len
Array of message lengths in bytes.
pa_hash
Array of pointers to the resultant digests.
Description
The function uses the SM3 hashing scheme to compute digest values of the entire (non-streaming) input messages passed by
pa_msg
parameter in parallel. The lengths of the messages are specified in
len
array and can be different in different buffers. Produced hash values are stored in the memory locations specified by the
pa_hash
parameter.
Return Values
The
mbx_sm3_msg_digest_mb16
function returns the status that indicates whether the operation completed successfully or not. The status value of 0 indicates that digest values for all messages were computed successfully. In case of non-zero status value,
MBX_GET_HIGH_PART_STS16()
and
MBX_GET_LOW_PART_STS16()
can help to get the low and high parts of the
mbx_status16
, which can be analyzed separately with
MBX_GET_STS()
call. The low part includes first eight statuses, while the high part includes remaining 8 statuses for each operation.
