A class for creating random secret keys. This class will do its best to create a random secret key that’s as secure as possible, using whatever methods are available on the current platform. For example:
generator = Rails::SecretKeyGenerator("some unique identifier, such as the application name") generator.generate_secret # => "f3f1be90053fa851... (some long string)"
GENERATORS = [ :secure_random, :win32_api, :urandom, :openssl, :prng ].freeze
