Today, core Java APIs lack high quality hash functions, and 3rd party implementations provide sub-optimal performance. As non-cryptographic hash function are important building blocks of software, this is a major bummer for developers.
Generally, the selection of available hash functions is plenty, and in the last decade, many new hash functions emerged with very good hashing properties. Surprisingly, the core Java API just still offers Adler32 and CRC32, which were designed as checksums many years ago. Of course, there are many hash implementations available outside of the core Java API. However, Continue reading
