I believe if you're hell-bent on pure Perl, there is no faster thing than the CRC32 for "sufficiently good" hashing. Enough work has gone into CRC32 to make it fast, as it has been in use for a long time. Oh - there even is a module for it - CRC32

But why not simply use Digest::MD5 ? I think it's core nowadays, and there even is a (slow) pure Perl version available ...

Update:Added link to the CRC32 module

perl -MHTTP::Daemon -MHTTP::Response -MLWP::Simple -e ' ;    # The  
$d = new HTTP::Daemon and fork and getprint $d->url and exit;#spider
($c = $d->accept())->get_request(); $c->send_response( new   #in the
HTTP::Response(200,$_,$_,qq(Just another Perl hacker\n))); ' #  web
