Webb30 apr. 2013 · SM3 [12] is the Chinese cryptographic hash standard which was announced in 2010 and designed by Wang et al. It is based on the Merkle–Damgård design and its compression function can be seen as a block cipher used in Davies–Meyer mode. It uses message block of length 512 bits and outputs hash value of length 256 bits.

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: ionrax luxury seat set
