CityHash, a family of hash functions for strings. Introduction === CityHash provides hash functions for strings. The functions mix the input bits thoroughly but are not suitable for cryptography. See "Hash Quality," below, for details on how CityHash was tested and so on. We provide reference...
Continuation of our technical discussion of how Java's String hash code function works, and implications for other hash functions.
Version 1.1 Introduction === A general overview of hash functions and their use is available in the file Understanding_Hash_Functions in this directory. It may be helpful to read it before using FarmHash. FarmHash provides hash functions for strings and other data. The functions mix the input...
For a number of years, MD5 was the most popular and often used hash function.The hash functions MD2, MD4, MD5, and MD6 are members of the MD family. It was adopted as the RFC 1321, Internet Standard. It is a 128-bit hash function. In the software industry, MD5 digests are ...

In MySQL 5.7.5, we introduced new functions for encoding and decoding Geohash data. Geohash is a system for encoding and decoding longitude and latitude coordinates in the WGS 84 coordinate system, into a text string. In this blog post we will take a brief look at a simple example to ...
Cryptographic hash functions must be deterministic. In other words, for any given input, a hash function must always give the same result. If you put in the same input a hash function must produce the same exact output. As mentioned above, the inputs to a hash function can be of any le...
Lightning fast hash functions for browsers and Node.js using hand-tuned WebAssembly binaries (MD4, MD5, SHA-1, SHA-2, SHA-3, Keccak, BLAKE2, BLAKE3, PBKDF2, Argon2, bcrypt, scrypt, Adler-32, CRC32, CRC32C, RIPEMD-160, HMAC, xxHash, SM3, Whirlpool). Lates
Geohash is a system for encoding latitude and longitude coordinates of arbitrary precision into a text string. Geohash values are strings that contain only characters chosen from"0123456789bcdefghjkmnpqrstuvwxyz". The functions in this section enable manipulation of geohash values, which provides ap...
