"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. " - Sm3 hash function
