WebxxHash is an Extremely fast Hash algorithm, processing at RAM speed limits. Code is highly portable, and produces hashes identical across all platforms (little / big endian). … WebPearson hashing is a hash function designed for fast execution on processors with 8-bit registers. Given an input consisting of any number of bytes, it produces as output a single byte that is strongly dependent on every byte of the input. Its implementation requires only a few instructions, plus a 256-byte lookup table containing a permutation ...

WebSep 7, 2015 · SHA-1 is fastest, then the SHA-2 family: SHA-256, SHA-384, SHA-512. For some reason though, SHA-384 clocks in a lot faster than either SHA-256 or SHA-512. Finally, there are various classes for any given algorithm. Many have “managed” and regular versions and sometimes there is a “CryptoServiceProvider” version. Webcycl./hash: The average of the Small key speed test for 1-31 byte keys. The smaller the better. cycl./map: The result of the Hashmap test for /usr/dict/words with fast C++ hashmap get queries, with the standard deviation in brackets. This tests the inlinability of the hash function in practise (see size). blackwater creek koi food for sale
