Random Sources is a Ruby gem that provides genuine random numbers, generated by processes fundamentally governed by inherent uncertainty instead of some pseudo-random number algorithm. It uses HTTP services from different online providers.
Install the gem:
$ [sudo] gem install random_sources
Then depending on your project you may:
Require the gem (if a ruby project):
or add it to your Gemfile (if you’re on Rails):
gem 'random_sources', :git => 'git://github.com/xuanxu/random_sources.git'
Your entry point is the RandomSources module. With it you can get a list of supported providers and instantiate any of them:
RandomSources.list #=> "HotBits, RandomOrg" RandomSources.generator 'RandomOrg' #=> <RandomSources::RandomOrg>
The current version includes two online sources. Each of them is managed by its own class.
Usually the provider assigns a quota of bits per day and IP, so use it properly and check the conditions of use in their websites.
