p5-Bytes-Random-Secure

Generate cryptographically-secure random bytes

Bytes::Random::Secure provides two interfaces for obtaining crypto-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 functions that can be used any time you need a string of a specific number of random bytes. The random bytes are available as simple strings, or as hex-digits, Quoted Printable, or MIME Base64. There are equivalent methods available from the OO interface, plus a few others. This module can be a drop-in replacement for Bytes::Random, with the primary enhancement of using a cryptographic-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.
