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

# Bases de Datos SQL (Relacionales) { #sql-relational-databases }

**FastAPI** no requiere que uses una base de datos SQL (relacional). Pero puedes utilizar **cualquier base de datos** que desees.

Aquí veremos un ejemplo usando [SQLModel](https://sqlmodel.tiangolo.com/).
