SMHasher currently appends zeros as a test. It is more practical to try all values in the range 0..255 as appendage. Hashes may break earlier on some values, zero may even be a less of a security thre…

Currently hash quality should be strong based on the properties of aes and splitmix. But verification of this is limited to manual inspection and basic unit tests. SMHasher is a good hasher test suite…

Should I submit it as "tabulation" or just replace multiply_shift, since the current implementatio…
