Makerand(3) User Contributed Perl Documentation Makerand(3)NAMECrypt::Makerand - Perl extension for the truerand library
SYNOPSIS
use Crypt::Makerand;
$rand = Crypt::Makerand::trand32();
DESCRIPTION
Uses the truerand library to generate a random 32 bit number.
The basic idea here is that between clock "skew" and various hard-to-
predict OS event arrivals, counting a tight loop will yield a little
(maybe a third of a bit or so) of "good" randomness per interval clock
tick. This seems to work well even on unloaded machines. If there is
a human operator at the machine, you should augment truerand with other
measure, like keyboard event timing.
On server machines (e.g., when you need to generate a Diffie-Hellman
secret) truerand alone may be good enough.
