## 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`.

```
read EC key
writing EC key
```

Alternatively, use the following command to generate a private ECDSA key protected by a password:

```sh
openssl ecparam -genkey -name prime256v1 | openssl ec -aes256 -out private.key -passout pass:PASSWORD
```

#### 3.2.2 Generate a private key with RSA

Use the following command to generate a private key with RSA:

```sh
openssl genrsa -out private.key 2048
```
