It seems that, [ideally, yes](https://en.m.wikipedia.org/wiki/Hash_function).

But “Note that this criterion only requires the value to be _uniformly distributed_ , not _random_ in any sense. A good randomizing function is (barring computational efficiency concerns) generally a good choice as a hash function, but the converse need not be true.”
