The Fash Fast Hash Functions

Douglas Crockford 2017-04-30 Public Domain

The Fash functions do rapid hashing and random number generation with multiplication.

This package contains seven program files:

fash.h              A C header file
uint64.h            Typedef include for uint64
fash.c              An implementation in portable C
fash64.x64.asm      A fast implementation of fash64 in assembly language
fash256.x64.asm     A fast implementation of fash256 in assembly language
rash64.x64.asm      A fast implementation of rash64 in assembly language
srash64.x64.asm     A fast implementation of srash64 in assembly language

This package also contains descriptions of the functions:

fash64.html         Practical hashing
fash256.html        Secure hashing
rash64.html         Practical random numbers
srash64.html        Secure random numbers
