NAME

Crypt::Komihash - Komihash implementation in Perl

SYNOPSIS

use Crypt::Komihash qw(komihash komihash_hex komirand_seed komirand64);

my $input = "Hello world";
my $seed  = 0;

my $num     = komihash($input, $seed);     # 3745467240760726046
my $hex_str = komihash_hex($input, $seed); # 33fa929c7367d21e

komirand_seed($seed1, $seed2);
my $rand    = komirand64();

DESCRIPTION

Komihash is a super fast modern hashing algorithm that converts strings into 64bit integers. Mainly designed for hash-table, hash-map, and bloom-filter uses. As a bonus, Komihash also includes a pseudo random number generator.

Note: This module requires a 64bit CPU

METHODS

$num = komihash($bytes, $seed = 0)

returns 64bit integer hash for the given input and seed.

$hex = komihash_hex($bytes, $seed = 0)

returns hex string hash for the given input and seed.

komirand_seed($seed1, $seed2)

seed the Komirand PRNG with two 64bit unsigned integers

$num = komirand64()

returns a random 64bit unsigned integer
