Managing environment variables securely is a critical aspect of modern software development. Traditional methods like dotenv have served developers well but come with limitations, especially in terms of security and cross-platform compatibility. Enter dotenvx, the next-generation tool designed to overcome these challenges.

This comprehensive guide will walk you through the installation, configuration, and programmatic access of environment variables using dotenvx in Node.js, Python, Ruby, and Java. Learn how to leverage encrypted environment variables, ensure secure configuration management, and streamline your development process across multiple platforms.

dotenvx uses a pair of public and private keys to securely encrypt and decrypt environment variables. Here’s how these keys are created and used:

DOTENV_PUBLIC_KEY is used to encrypt environment variables. This key is safe to be included in the encrypted .env file because it cannot be used to decrypt the variables.
