The values returned by [sha256.New] and [sha256.New224] now also implement the [encoding.BinaryAppender] interface...

Nesta seção, veremos como usar outros middlewares.

## Adicionando middlewares ASGI

Como o **FastAPI** é baseado no Starlette e implementa a especificação <abbr title="Asynchronous Server Gateway Interface">ASGI</abbr>, você pode usar qualquer middleware ASGI.

The value returned by [New] now also implements the [encoding.BinaryAppender] interface....
