A simple library for generating secure randomness (strings, integers, shuffling) using MCRYPT_DEV_URANDOM

Simply Random

tested on 5.6, 7.0, 7.1 and HHVM

What is this library?

This is a simple library for random number generation using random_bytes.
This library can generate strong, cryptographically secure random numbers, and other useful random values.

Dependencies

This library depends on random_bytes or the polyfill provided by ParagonIE. If provided as a native extension the kernel CSPRNG is used. The polyfill handles checking for appropriate sources of entropy if this is not available.

Installation

Simply use composer require blocktrail/simply-random ~1.0.

Usage

Please refer to test.php for example usage.

Most of the code used in this library was originally written by ircmaxell for random_compat. This library initially began as a fork with reduced complexity, and strong dependency on mcrypt.
