# check .env.keys for your privateKey
$ DOTENV_PRIVATE_KEY_PRODUCTION="122...0b8" dotenvx run -- node index.js
[dotenvx@1.X.X] injecting env (2) from .env.production
Hello production encrypted
```

Note the `DOTENV_PRIVATE_KEY_PRODUCTION` ends with `_PRODUCTION`. This instructs dotenvx run to load the `.env.production` file.

Decrypt your encrypted `.env.ci` by setting `DOTENV_PRIVATE_KEY_CI` before `dotenvx run`. Alternatively, this can be already set on your server or cloud provider.

```sh
$ touch .env.ci
$ dotenvx set HELLO "ci encrypted" -f .env.ci
$ echo "console.log('Hello ' + process.env.HELLO)" > index.js
