Method: Rails::Application#key_generator

Defined in:
railties/lib/rails/application.rb

#key_generator(secret_key_base = self.secret_key_base) ⇒ Object

Returns a key generator (ActiveSupport::CachingKeyGenerator) for a specified secret_key_base. The return value is memoized, so additional calls with the same secret_key_base will return the same key generator instance.
