## Encrypted Private Key

MinIO supports encrypted KES client private keys. Therefore, you can use
an password-protected private keys for `MINIO_KMS_KES_KEY_FILE`.

When using password-protected private keys for accessing KES you need to
provide the password via:

```
export MINIO_KMS_KES_KEY_PASSWORD=<your-password>
```
