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 encour-
       aged 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.
