require 'random/formatter'

# == 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 'securerandom'
#
# It supports the following secure random number generators:
#
# * openssl
# * /dev/urandom
# * Win32
#
# SecureRandom is extended by the 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 SecureRandom such as
# +SecureRandom.hex+.
#
# If a secure random number generator is not available,
# +NotImplementedError+ is raised.

  VERSION = "0.4.1"

    #
