WebbPointer to the SM3_CTX_mb16 context. Description The function digests the current streams of input messages passed by pa_msg parameter. The specified messages lengths are passed through len array. You can call the function several times with the same p_state to produce intermediate hashes values. WebbThe class HashFunction is defined in botan/hash.h. Using a hash function is typically split into three stages: initialization, update, and finalization (often referred to as a IUF interface). The initialization stage is implicit: after creating a hash function object, it is ready to process data. Then update is called one or more times.
