Perl extension to generate cryptographically-secure random bytes

Bytes::Random::Secure provides two interfaces for obtaining crypt-quality random bytes. The simple interface is built around plain functions. For greater control over the Random Number Generator's seeding, there is an Object Oriented interface that provides much more flexibility.

The "functions" interface provides five functions that can be used any time you need a string (or MIME Base64 representation, or hex-digits representation, or Quoted Printable representation) of a specific number of random bytes. There are equivalent methods available via the OO interface.

Bytes::Random::Secure can be a drop-in replacement for Bytes::Random, with the primary enhancement of using a much higher quality random number generator to create the random data. The random_bytes function emulates the user interface of Bytes::Random's function by the same name. But with Bytes::Random::Secure the random number generator comes from Math::Random::ISAAC, and is suitable for cryptographic purposes. The harder problem to solve is how to seed the generator. This module uses Crypt::Random::Seed to generate the initial seeds for Math::Random::ISAAC.
