NAME

       Apache::Session::Generate::MD5 - Use MD5 to create random object IDs

SYNOPSIS

        use Apache::Session::Generate::MD5;

        $id = Apache::Session::Generate::MD5::generate();

DESCRIPTION

       This module fulfills the ID generation interface of Apache::Session.  The IDs are
       generated using a two-round MD5 of a random number, the time since the epoch, the process
       ID, and the address of an anonymous hash.  The resultant ID number is highly entropic on
       Linux and other platforms that have good random number generators.  You are encouraged to
       investigate the quality of your system's random number generator if you are using the
       generated ID numbers in a secure environment.

       This module can also examine session IDs to ensure that they are, indeed, session ID
       numbers and not evil attacks.  The reader is encouraged to consider the effect of bogus
       session ID numbers in a system which uses these ID numbers to access disks and databases.

       This modules takes one argument in the usual Apache::Session style.  The argument is
       IDLength, and the value, between 0 and 32, tells this module where to truncate the session
       ID.  Without this argument, the session ID will be 32 hexadecimal characters long,
       equivalent to a 128-bit key.
