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

       The JHash implementation was written by Bob Jenkins <bob_jenkins [at] burtleburtle [dot] net>.

       This perl extension was written by Andrew Towers <mariofrog [at] bigpond [dot] com>.

       A few mods were added by James Freeman <airmedical [at] gmail [dot] com>).

       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.

       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)

       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)

       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

           use Digest::JHash qw(jhash);

           $digest = jhash($data);

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

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