The minimal stuff needed from Bytes::Random::Secure, with no dependencies.
This module provides a simple to use Cryptographically Secure Pseudo-Random Number Generator (CSPRNG) built around the ISAAC algorithm. Its methods include irand for unsigned 32-bit integers, bytes for simple random bytes, and string_from for characters chosen at random from a bag of candidates. It also reliably seeds the CSPRNG from a secure source on a wide variety of platforms.

The CPAN Module Bytes::Random::Secure also produces high quality pseudo-randomness using the ISAAC cryptographically secure pseudo-random number generation algorithm, seeded using cryptographically secure entropy sources on a wide variety of operating systems. It has many configuration options. And provides both a functions and an object interface. But it has several dependencies, and its configurability and its user-interface, while flexible and useful, may expose more complexity than most use-cases require.
Bytes::Random::Secure::Tiny's goal is to have no dependencies outside of the Perl core, and a simple interface that presents a minimal amount of configuration. We asked ourselves, what are the essentials, and how can we achieve them in the most light-weight way? This module is the answer we came up with. We believe that this module will satisfy 90% of those users who were using Bytes::Random::Secure, but will do so with reduced complexity, a smaller user interface, and none of the frustration that dependencies can bring.
See the documentation for Bytes::Random::Secure::Tiny for more information.
