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

#### Случайный элемент { #a-random-item }

С помощью `data.items()` мы получаем <abbr title="Объект, по которому можно итерироваться циклом for, например список, множество и т. п.">итерируемый объект</abbr> с кортежами, содержащими ключ и значение для каждого элемента словаря.

Мы превращаем этот итерируемый объект в обычный `list` через `list(data.items())`.
