$Id: PP.pm,v 0.12 2013/02/28 03:18:03 dankogai Exp $
SYNOPSIS
use Digest::SipHash::PP qw/siphash/;
my $seed = pack 'C16', 0 .. 0xF; # 16 chars long
my $str = "hello world!";
my ( $lo, $hi ) = siphash( $str, $seed );
# $lo = 0x10cf32e0, $hi == 0x7da9cd17
my $u32 = siphash( $str, $seed )
# $u32 = 0x10cf32e0
use Config;
if ( $Config{use64bitint} ) {
use Digest::SipHash qw/siphash64/;
my $uint64 = siphash64( $str, $seed ); # scalar context;
# $uint64 == 0x7da9cd1710cf32e0
}DESCRIPTION
This module is identical to Digest::SipHash except implementation. This module is not meant to be practical; written just for the sake of curiosity.
IMPLEMENTATION
For the sake of 32-bit compatibility, this module uses Math::BigInt for 64-bit operations on which SipHash heavily relies.
EXPORT
siphash(), siphash32() and siphash64() on demand.
:all to all of above
