NAME

       Digest::JHash - Perl extension for 32 bit Jenkins Hashing Algorithm

SYNOPSIS

           use Digest::JHash qw(jhash);

           $digest = jhash($data);

           # note that calling jhash() directly like this is the fastest way:

           $digest = Digest::JHash::jhash($data);

DESCRIPTION

       The "Digest::JHash" module allows you to use the fast JHash hashing algorithm developed by
       Bob Jenkins from within Perl programs. The algorithm takes as input a message of arbitrary
       length and produces as output a 32-bit "message digest" of the input in the form of an
       unsigned long integer.

       Call it a low calorie version of MD5 if you like.

       See http://burtleburtle.net/bob/hash/doobs.html for more information.

FUNCTIONS

       jhash($data)
           This function will calculate the JHash digest of the "message" in $data and return a
           32 bit integer result (an unsigned long in the C)

EXPORTS

       None by default but you can have the jhash() function if you ask nicely.  See below for
       reasons not to use Exporter (it is slower than a direct call)

SPEED NOTE

       If speed is a major issue it is roughly twice as fast to do call the jhash() function like
       Digest::JHash::jhash('message') than it is to import the jhash() method using Exporter so
       you can call it as simply jhash('message').  There is a short script that demonstrates the
       speed of different calling methods (direct, OO and Imported) in examples/oo_vs_func.pl
