Apache::Session::GenerUser:Contributed Perl DApache::Session::Generate::MD5(3)NAMEApache::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.
