When it comes to hashing, sometimes 64 bit is not enough, for example, because of birthday paradox — the hacker can iterate through random entities and it can be proven that with some constant probability they will find a collision, i.e. two different objects will have the same hash. is around 4 billion objects and with the current power capacity in each computer it is certainly achievable. That’s why we need sometimes to advance the bitness of hashing to at least 128 bits. Unfortunately, it c...
