module Gem::SecureRandom

Secure random number generator interface. ↑

This library is an interface to secure random number generators which are suitable for generating session keys in HTTP cookies, etc.

You can use this library in your application by requiring it:

require 'bundler/vendor/securerandom/lib/securerandom'

It supports the following secure random number generators:

  • openssl

  • /dev/urandom

  • Win32

Bundler::SecureRandom is extended by the Bundler::Random::Formatter module which defines the following methods:

  • alphanumeric

  • base64

  • choose

  • gen_random

  • hex

  • rand

  • random_bytes

  • random_number

  • urlsafe_base64

  • uuid

These methods are usable as class methods of Bundler::SecureRandom such as Bundler::SecureRandom.hex.

If a secure random number generator is not available, NotImplementedError is raised.
