The .env file format starts where the developer starts - in development. It is added to each project but NOT committed to source control. This gives the developer a single secure place to store sensitive application secrets.
Can you believe that prior to introducing the .env file, almost all developers stored their secrets as hardcoded strings in source control. That was only 10 years ago!
Here's an example of what a .env file looks like:
# example .env file STRIPE_API_KEY=scr_12345 TWILIO_API_KEY=abcd1234
It is purposefully simple because, as security professionals, we know that complexity is the enemy of security.
You can read more about how it works here (or at other implementations here, here, here). It is the gold standard for securing development secrets - proven and trusted by millions of developers around the world.
But the world has changed and developers manage secrets at far greater scale than a decade ago. Today it's difficult to securely share .env files between machines, environments, and team members. As a result, developers often share secrets over Slack, email, text message, and post-it notes. It's not scaleable and fraught with security risks. For a CTO or CSO it is a risk they should not take.
Luckily, that is changing. We have been extending the .env file format to support secure sharing.
The .env file format will still be at the center of security. But we have added two new extensions. They are not required. They are optional, but we highly recommend them for teams. They are the:
In the next set of security docs you can read about how these work alongside your .env files to significantly improve security. This is the next great leap forward in application secrets security, and like the original .env file format we have worked hard to minimize complexity in order to increase security.
