WebOct 22, 2015 · Java conveniently provides fast hash functions in its Arrays class. The Java engineers like to use a simple polynomial hash function: for (int i = 0; i < len; i++) { h = 31 * h + val[i]; } That function is very fast. Unfortunately, as it is written, it is not optimally fast for long arrays. The problem comes from the multiplication.

WebMay 19, 2016 · The "birthday paradox" places an upper bound on collision resistance: if a hash function produces N bits of output, an attacker who computes only $2^{N/2}$ (or $ \sqrt{2^N}$) hash operations on random input is likely to find two matching outputs.
