# -*- coding: us-ascii -*-

# == 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`.
#
# === Examples
#
# Generate random hexadecimal strings:
#
#   require 'securerandom'
#
#   SecureRandom.hex(10) #=> "52750b30ffbc7de3b362"
#   SecureRandom.hex(10) #=> "92b15d6c8dc4beb5f559"
#   SecureRandom.hex(13) #=> "39b290146bea6ce975c37cfc23"
#
# Generate random base64 strings:
#
#   SecureRandom.base64(10) #=> "EcmTPZwWRAozdA=="
#   SecureRandom.base64(10) #=> "KO1nIU+p9DKxGg=="
#   SecureRandom.base64(12) #=> "7kJSM/MzBJI+75j8"
#
# Generate random binary strings:
#
#   SecureRandom.random_bytes(10) #=> "\016\t{\370g\310pbr\301"
#   SecureRandom.random_bytes(10) #=> "\323U\030TO\234\357\020\a\337"
#
# Generate alphanumeric strings:
#
#   SecureRandom.alphanumeric(10) #=> "S8baxMJnPl"
#   SecureRandom.alphanumeric(10) #=> "aOxAg8BAJe"
#
# Generate UUIDs:
#
#   SecureRandom.uuid #=> "2d931510-d99f-494a-8c67-87feb05e1594"
#   SecureRandom.uuid #=> "bad85eb9-0713-4da7-8d36-07a8e4b00eab"
