setting the env. variable `MINIO_KMS_SECRET_KEY`. It expects the following
format:

```sh
MINIO_KMS_SECRET_KEY=<key-name>:<base64-value>
```

First generate a 256 bit random key via:

```sh
$ cat /dev/urandom | head -c 32 | base64 -
OSMM+vkKUTCvQs9YL/CVMIMt43HFhkUpqJxTmGl6rYw=
```

Now, you can set `MINIO_KMS_SECRET_KEY` like this:

```sh

from base64 import b64encode

from fastapi import FastAPI, Security
from fastapi.security import HTTPBasic, HTTPBasicCredentials
from fastapi.testclient import TestClient

app = FastAPI()

security = HTTPBasic(realm="simple", description="HTTPBasic scheme")


@app.get("/users/me")
def read_current_user(credentials: HTTPBasicCredentials = Security(security)):
    return {"username": credentials.username, "password": credentials.password}

			crypto.MetaSealedKeyS3:       base64.StdEncoding.EncodeToString(make([]byte, 64)),
			crypto.MetaKeyID:             "kms-key",
			crypto.MetaDataEncryptionKey: "m-key",
		},
		encryptionType: encrypt.S3,
		err:            nil,
	}, // 4
	{
		headers:    http.Header{},
		copySource: true,
		metadata: map[string]string{
			crypto.MetaSealedKeyS3:       base64.StdEncoding.EncodeToString(make([]byte, 64)),
