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

        if (context != null) {
            System.arraycopy(context, 0, input, pos, context.length);
        }

        // Use SHA-256 for derivation (placeholder)
        try {
            java.security.MessageDigest md = java.security.MessageDigest.getInstance("SHA-256");
            byte[] hash = md.digest(input);
            System.arraycopy(hash, 0, derived, 0, Math.min(length, hash.length));
