   2   # A class for creating random secret keys. This class will do its best to create a
   3   # random secret key that's as secure as possible, using whatever methods are
   4   # available on the current platform. For example:
   5   #
   6   #   generator = Rails::SecretKeyGenerator("some unique identifier, such as the application name")
   7   #   generator.generate_secret     # => "f3f1be90053fa851... (some long string)"
   8   #
   9   # This class is *deprecated* in Rails 2.2 in favor of ActiveSupport::SecureRandom.
  10   # It is currently a wrapper around ActiveSupport::SecureRandom.

  16     # the current platform.
