- Run MinIO without a KMS. In this case all IAM data will be stored in plain-text.
- Run MinIO with a single secret key. MinIO supports a static cryptographic key
  that can act as minimal KMS. With this method all IAM data will be stored
  encrypted. The encryption key has to be passed as environment variable.
- Run MinIO with KES (minio/kes) in combination with any supported KMS as
  secure key store. For example, you can run MinIO + KES + Hashicorp Vault.
