DOTENV_PRIVATE_KEY_PRODUCTION=key dotenvx run

Decrypt your encrypted `.env.production` by setting `DOTENV_PRIVATE_KEY_PRODUCTION` before dotenvx run.

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

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

Alternatively, this can be already set on your server or cloud provider.

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