Abstract
FNV (Fowler/Noll/Vo) is a fast, non-cryptographic hash algorithm with good dispersion that has been widely used and is referenced in a number of standards documents. The purpose of this document is to make information on FNV and open-source code performing all specified sizes of FNV conveniently available to the Internet community.
