A middleware doesn't have to be made for FastAPI or Starlette to work, as long as it follows the ASGI spec.

In general, ASGI middlewares are classes that expect to receive an ASGI app as the first argument.

So, in the documentation for third-party ASGI middlewares they will probably tell you to do something like:

```Python
from unicorn import UnicornMiddleware

To summarize for any encrypted object there exists (at least) three different keys:

- [OEK](#oek): A secret and unique key used to encrypted the object, stored in an encrypted form as part of the object metadata and only loaded to RAM in plaintext during en/decrypting the object.
- [KEK](#kek): A secret and unique key used to en/decrypt the OEK and never stored anywhere. It is(re-)generated whenever en/decrypting an object using an external secret key and public parameters.

Se você já sabe o que são "variáveis de ambiente" e como usá-las, pode pular esta seção.

///

Uma variável de ambiente (também conhecida como "**env var**") é uma variável que existe **fora** do código Python, no **sistema operacional**, e pode ser lida pelo seu código Python (ou por outros programas também).
