This is why you should NEVER trust software developers to make security decisions unless certified to do so. True randomness is challenging to achieve, because computers are inherently predictable. Pseudo-randomness is an intended process to intentionally achieve randomness in spite of this high predictability, often through use of physical or electromagnetic criteria outside the computing machine.

Hash algorithms are none of that. They are not pseudo-randomness merely because a software developer merely wishes them to be so. Hash algorithms are intentionally designed to achieve high reproducibility in that a given set of input should always result in the same hash sequence as output. That intended reproducibility is by definition not random.
