WebAug 28, 2024 · We’ve established that a hash function can be thought of as a random oracle that, given some input (i.e., an arbitrarily-sized sequence of bits) returns a “random,” fixed-size input (i.e., 256 bits) and will always return that same given that same as input. (We assume the output size is 256 bits. We’ll explain later why.) WebAs the salt is part of the hash, you store the salt on the database and the password on the user.

For any given input, this Oracle should return a truly uniformly random output. This is ideal of how hash functions work, so any hash function that isn't uniformly random is not behaving the same way as a random Oracle. So yes, hash functions should have uniformly distributed values.
