class ActiveSupport::EncryptedConfiguration

Provides convenience methods on top of EncryptedFile to access values stored as encrypted YAML.

Values can be accessed via Hash methods, such as fetch and dig, or via dynamic accessor methods, similar to OrderedOptions.

my_config = ActiveSupport::EncryptedConfiguration.new(...)
my_config.read # => "some_secret: 123\nsome_namespace:\n  another_secret: 456"

my_config[:some_secret]
# => 123
my_config.some_secret
# => 123
my_config.dig(:some_namespace, :another_secret)
# => 456
my_config.some_namespace.another_secret
# => 456
my_config.fetch(:foo)
# => KeyError
my_config.foo!
# => KeyError
