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

  /**
   * The maximum value of an ASCII character.
   *
   * @since 9.0 (was type {@code int} before 12.0)
   */
  public static final char MAX = 127;

  /** A bit mask which selects the bit encoding ASCII character case. */
  private static final char CASE_MASK = 0x20;

  /**
   * Returns a copy of the input string in which all {@linkplain #isUpperCase(char) uppercase ASCII

it was perfectly round, she found this a very difficult question.
However, at last she stretched her arms round it as far as they
would go, and broke off a bit of the edge with each hand.

  `And now which is which?' she said to herself, and nibbled a
little of the right-hand bit to try the effect:  the next moment
she felt a violent blow underneath her chin:  it had struck her
foot!

It can be used by third party applications and systems.

And it can also be used by yourself, to debug, check and test the same application.

## The `password` flow { #the-password-flow }

Now let's go back a bit and understand what is all that.

The `password` "flow" is one of the ways ("flows") defined in OAuth2, to handle security and authentication.
