NAME

Bytes::Random::XS - Perl extension to generate random bytes.

SYNOPSIS

use Bytes::Random::XS qw/random_bytes/;

my $bytes = random_bytes( $number_of_bytes );

DESCRIPTION

This module provides the random_bytes function which allows you to generate specified number of random bytes. It uses exactly the same algorithm as Bytes::Random, but it's implemented in XS, so it's much faster (see "BENCHMARKS" section).

BENCHMARKS

Comparison of Bytes::Random and Bytes::Random::XS performance:

# random_bytes(64)

                  Rate    B::R@0.02 B::R::X@0.01
B::R@0.02      45903/s           --         -97%
B::R::X@0.01 1462857/s        3087%           --

EXPORT

Nothing is exported by default. random_bytes is an optional export.

CAVEATS

• This module is not intended to be cryptographically secure. If that concerns you, consider using Bytes::Random::Secure instead.

• Bytes::Random::XS is an XS module, which means it's not compatible with App::FatPacker. Bytes::Random is a pure Perl alternative that doesn't have this problem.
