### Authenticate

Click the "Authorize" button.

Use the credentials:

User: `johndoe`

Password: `secret`

### Get your own user data

### Authentifizieren

Klicken Sie auf den Button „Authorize“.

Verwenden Sie die Anmeldedaten:

Benutzer: `johndoe`

Passwort: `secret`.

### Die eigenen Benutzerdaten ansehen

| [**AssumeRole**](https://github.com/minio/minio/blob/master/docs/sts/assume-role.md)   | Let MinIO users request temporary credentials using user access and secret keys.                                                              |

### Understanding JWT Claims

> NOTE: JWT claims are only meant for WebIdentity and ClientGrants.

No, MinIO does not depend on any third-party KMS provider. You have three options here:

- Run MinIO without a KMS. In this case all IAM data will be stored in plain-text.
- Run MinIO with a single secret key. MinIO supports a static cryptographic key
  that can act as minimal KMS. With this method all IAM data will be stored
  encrypted. The encryption key has to be passed as environment variable.

### Flit

**FastAPI** utilise <a href="https://flit.readthedocs.io/en/latest/index.html" class="external-link" target="_blank">Flit</a> pour build, packager et publier le projet.

Après avoir activé l'environnement comme décrit ci-dessus, installez `flit` :

<div class="termy">

```console
$ pip install flit

---> 100%
```

</div>

Additionally, we create a `secret_name` for the hero, but so far, we are returning it everywhere, that's not very **secret**... 😅

We'll fix these things by adding a few **extra models**. Here's where SQLModel will shine. ✨

### Create Multiple Models

In **SQLModel**, any model class that has `table=True` is a **table model**.

	"errors"
	"io"
	"path"

	"github.com/minio/minio/internal/fips"
	"github.com/minio/minio/internal/hash/sha256"
	"github.com/minio/minio/internal/logger"
	"github.com/minio/sio"
)

// ObjectKey is a 256 bit secret key used to encrypt the object.
// It must never be stored in plaintext.
type ObjectKey [32]byte

// GenerateKey generates a unique ObjectKey from a 256 bit external key

func (r *Config) PopulatePublicKey(arn arn.ARN) error {
	pCfg := r.arnProviderCfgsMap[arn]
	if pCfg.JWKS.URL == nil || pCfg.JWKS.URL.String() == "" {
		return nil
	}

	// Add client secret for the client ID for HMAC based signature.
	r.pubKeys.add(pCfg.ClientID, []byte(pCfg.ClientSecret))

	client := &http.Client{
		Transport: r.transport,
	}

	resp, err := client.Get(pCfg.JWKS.URL.String())

### Configure Keycloak Realm

- Go to Clients
  - Click on account
    - Settings
    - Change `Access Type` to `confidential`.
    - Save
  - Click on credentials tab
    - Copy the `Secret` to clipboard.
    - This value is needed for `MINIO_IDENTITY_OPENID_CLIENT_SECRET` for MinIO.

- Go to Users
  - Click on the user
