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. Webb10 nov. 2024 · Many “old” program still use Keccak, and do not upgrade to official SHA-3 standard. “old” code based on Keccak does not generate the same hash value as SHA-3 does. So, if using a “sha3” library, you should be crystal clear that the library is based on Keccak or based on standard SHA-3.
