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. A simple solution is doing a test for empty input: ShangMi 3 (SM3) is a cryptographic hash function used in the Chinese National Standard.
