SM3 Hash Functions

SM3 functionality supports two scenarios of data processing:
  1. Processing the entire messages with known length: mbx_sm3_msg_digest_mb16().
  2. Streaming processing, when the lengths of the messages are initially unknown: mbx_sm3_init_mb16(), mbx_sm3_update_mb16(), mbx_sm3_final_mb16().
Functions that work in streaming mode operate with the public
SM3_CTX_mb16
context. “Public” means that the structure of this context is open and fields of this context are accessible to users. For more information refer to
crypto_mb/sm3.h
. To get started with this context, you need to allocate memory for it and call the
mbx_sm3_init_mb16()
function to set it up.
