Encrypt a .env file in uv

Prerequisites

To get the most out of this guide, you’ll need to:

0. Setup

Create a uv project.

$ uv init hello-world
$ cd hello-world

Get the Dotenvx Python SDK.

$ uv add python-dotenvx

And the CLI to encrypt files.

$ curl -sfS https://dotenvx.sh | sh

Encrypt your .env file.

$ dotenvx encrypt

Then inject your encrypted secrets at runtime.

import os
from dotenvx import load_dotenv

load_dotenv()

print(f"HELLO: {os.getenv('HELLO')}")

Run it with uv.

$ uv run main.py
