The bloom filter hashes the entries with MD5 and treats the resulting 128-bit
hash as 2 distinct 64-bit hash values, interpreted as unsigned integers
using 2's complement encoding.
These two hash values, named h1 and h2, are then used to compute the
hash_count hash values using the formula, starting at i=0:
h(i) = h1 + (i * h2)
These resulting values are then taken modulo the number of bits in the bloom
filter to get the bits of the bloom filter to test for the given entry.
