-- | Creates a display name for a customer master key. An alias can be used to
-- identify a key and should be unique. The console enforces a one-to-one
-- mapping between the alias and a key. An alias name can contain only
-- alphanumeric characters, forward slashes (/), underscores (_), and dashes
-- (-). An alias must start with the word "alias" followed by a forward slash
-- (alias/). An alias that begins with "aws" after the forward slash
-- (alias/aws...) is reserved by Amazon Web Services (AWS).
--
-- To associate an alias with a different key, call 'UpdateAlias'.
--
-- Note that you cannot create or update an alias that represents a key in
-- another account.
