From 4944ef59b95764a4b5333c7846f2f58dc62ffa5e Mon Sep 17 00:00:00 2001 From: Peter Palfrader Date: Wed, 17 Jul 2002 16:14:23 +0000 Subject: The cheap hashing function that was used for determining when to ping was replaced by md5. The local secret also is an input to the function so not all echolot pingers ping the same remailer at the same time. --- Echolot/Pinger.pm | 11 +++++------ 1 file changed, 5 insertions(+), 6 deletions(-) (limited to 'Echolot') diff --git a/Echolot/Pinger.pm b/Echolot/Pinger.pm index d996427..18f72f9 100644 --- a/Echolot/Pinger.pm +++ b/Echolot/Pinger.pm @@ -1,7 +1,7 @@ package Echolot::Pinger; # (c) 2002 Peter Palfrader -# $Id: Pinger.pm,v 1.14 2002/07/17 02:36:07 weasel Exp $ +# $Id: Pinger.pm,v 1.15 2002/07/17 16:14:23 weasel Exp $ # =pod @@ -22,13 +22,12 @@ use English; use Echolot::Pinger::Mix; use Echolot::Pinger::CPunk; -my @primes = qw{13 1997 173 1051 59 6 97883 197 3 2 109 127 7}; sub makeHash($) { my ($text) = @_; - my $sum = 0; - for (my $i=0; $i < length($text); $i++) { - $sum += ord( substr($text, $i, 1) ) * $primes[ $i % (scalar @primes) ]; - }; + + my $hash = Echolot::Tools::make_mac($text); + $hash = substr($hash, 0, 4); + my $sum = hex($hash); return $sum; }; -- cgit v1.2.3
