Lassen Sie uns nun die von **FastAPI** bereitgestellten Werkzeuge verwenden, um das zu erledigen.

### `OAuth2PasswordRequestForm`

Importieren Sie zunächst `OAuth2PasswordRequestForm` und verwenden Sie es als Abhängigkeit mit `Depends` in der *Pfadoperation* für `/token`:

// ## SSE-S3
//
// SSE-S3 can use either a master key or a KMS as root-of-trust.
// The en/decryption slightly depens upon which root-of-trust is used.
//
// ### SSE-S3 and single master key
//
// The master key is used to derive unique object- and key-encryption-keys.
// SSE-S3 with a single master key works as SSE-C where the master key is

You would probably do this just once, the first time, when setting everything up.

This Domain Name part is way before HTTPS, but as everything depends on the domain and the IP address, it's worth mentioning it here.

Now let's focus on all the actual HTTPS parts.

Further any secret key (apart from the KMS-generated ones) is 256 bits long. The KMS-generated keys may be 256 bits but this depends on the KMS capabilities and configuration.

Em muitos casos você pode ter (e deveria ter) um "proxy de saída" tratando HTTPS no topo, isso dependerá de como você fará o deploy da sua aplicação, seu provedor pode fazer isso pra você ou talvez seja necessário fazer você mesmo.
