#### 3.2.1 Generate a private key with ECDSA

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

```sh
openssl ecparam -genkey -name prime256v1 | openssl ec -out private.key
```

A response similar to this one should be displayed:

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

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

```sh

            this.mid = mid;
        }

        @Override
        public int getCommand() {
