WebFeb 12, 2024 · crc32_hash (): This the Hashing method. It hashes the key generated by the encode () method. It uses the Least-Significant-Bit-first order, sets the initial CRC to FFFFFFFF 16, and complements the final CRC. The CRC32 algorithm produces checksums that are so well distributed that we use it as a hashing function. WebJul 19, 2024 · CityHash is intended to be fast, under the constraint that it hash very well. For CPUs with the CRC32 instruction, CRC is speedy, but CRC wasn't designed as a hash function and shouldn't be used as one. CityHashCrc128 () is not a CRC, but it uses the CRC32 machinery.
