WebPurely additive hash functions such as CRC fail this stronger condition miserably. Clearly, a strong hash function should have a uniform distribution of hash values. Bret Mulvey proposes the use of a chi-squared test for uniformity, based on power of two hash table sizes ranging from 2 1 to 2 16. This test is considerably more sensitive than ...
